Would you like to build Perl so that the installation is relocatable, so that
library paths in @INC are determined relative to the path of the perl binary?
This is not advised for system Perl installs, or if you need to run setid
scripts or scripts under taint mode.
If this doesn't make any sense to you, just accept the default '$dflt'.

=head2 Relocatable @INC
To create a relocatable perl tree, use the following command line:
sh Configure -Duserelocatableinc
Then the paths in @INC (and everything else in %Config) can be
optionally located via the path of the perl executable.
That means that, if the string ".../" is found at the start of any
path, it's substituted with the directory of $^X. So, the relocation
can be configured on a per-directory basis, although the default with
"-Duserelocatableinc" is that everything is relocated. The initial
install is done to the original configured prefix.
This option is not compatible with the building of a shared libperl
("-Duseshrplib"), because in that case perl is linked with an hard-coded
rpath that points at the libperl.so, that cannot be relocated.
=head2 Site-wide Policy settings
After Configure runs, it stores a number of common site-wide "policy"
answers (such as installation directories) in the Policy.sh file.
If you want to build perl on another system using the same policy
defaults, simply copy the Policy.sh file to the new system's perl build
directory, and Configure will use it. This will work even if Policy.sh was
generated for another version of Perl, or on a system with a
different architecture and/or operating system. However, in such cases,

incpth (libpth.U):
This variable must precede the normal include path to get the
right one, as in "$incpath/usr/include" or "$incpath/usr/lib".
Value can be "" or "/bsd43" on mips.
inews (Loc.U):
This variable is defined but not used by Configure.
The value is the empty string and is not useful.
initialinstalllocation (bin.U):
When userelocatableinc is true, this variable holds the location
that make install should copy the perl binary to, with all the
run-time relocatable paths calculated from this at install time.
When used, it is initialized to the original value of binexp, and
then binexp is set to '.../', as the other binaries are found
relative to the perl binary.
installarchlib (archlib.U):
This variable is really the same as archlibexp but may differ on
those systems using AFS. For extra portability, only this variable
should be used in makefiles.
installbin (bin.U):

and indicates that the quadmath library __float128 long doubles
should be used when available.
usereentrant (usethreads.U):
This variable conditionally defines the USE_REENTRANT_API symbol,
which indicates that the thread code may try to use the various
_r versions of library functions. This is only potentially
meaningful if usethreads is set and is very experimental, it is
not even prompted for.
userelocatableinc (bin.U):
This variable is set to true to indicate that perl should relocate
@INC entries at runtime based on the path to the perl binary.
Any @INC paths starting ".../" are relocated relative to the directory
containing the perl binary, and a logical cleanup of the path is then
made around the join point (removing "dir/../" pairs)
useshrplib (libperl.U):
This variable is set to 'true' if the user wishes
to build a shared libperl, and 'false' otherwise.
usesitecustomize (d_sitecustomize.U):
This variable is set to true when the user requires a mechanism that
allows the sysadmin to add entries to @INC at runtime. This variable

of F<perl.dll>.
The address tables of DLLs are patched only once, when they are
loaded. The addresses of the entry points into DLLs are guaranteed to be
the same for all the programs which use the same DLL. This removes the
runtime fixup - once DLL is loaded, its code is read-only.
While this allows some (significant?) performance advantages, this makes life
much harder for developers, since the above scheme makes it impossible
for a DLL to be "linked" to a symbol in the F<.EXE> file. Indeed, this
would need a DLL to have different relocations tables for the
(different) executables which use this DLL.
However, a dynamically loaded Perl extension is forced to use some symbols
from the perl
executable, e.g., to know how to find the arguments to the functions:
the arguments live on the perl
internal evaluation stack. The solution is to put the main code of
the interpreter into a DLL, and make the F<.EXE> file which just loads
this DLL into memory and supplies command-arguments. The extension DLL
cannot link to symbols in F<.EXE>, but it has no problem linking

=item Dynamic Loading Problems With GNU as and GNU ld
If you have problems with dynamic loading using gcc on SunOS or
Solaris, and you are using GNU as and GNU ld, see the section
L</"GNU as and GNU ld"> above.
=item ld.so.1: ./perl: fatal: relocation error:
If you get this message on SunOS or Solaris, and you're using gcc,
it's probably the GNU as or GNU ld problem in the previous item
L</"GNU as and GNU ld">.
=item dlopen: stub interception failed
The primary cause of the 'dlopen: stub interception failed' message is
that the LD_LIBRARY_PATH environment variable includes a directory
which is a symlink to /usr/lib (such as /lib). See
README.solaris view on Meta::CPAN
It may be possible to use the Entropy Gathering Daemon (written in
Perl!), available from L<http://www.lothar.com/tech/crypto/>.
=head1 SunOS 4.x
In SunOS 4.x you most probably want to use the SunOS ld, /usr/bin/ld,
since the more recent versions of GNU ld (like 2.13) do not seem to
work for building Perl anymore. When linking the extensions, the
GNU ld gets very unhappy and spews a lot of errors like this
... relocation truncated to fit: BASE13 ...
and dies. Therefore the SunOS 4.1 hints file explicitly sets the
ld to be F</usr/bin/ld>.
As of Perl 5.8.1 the dynamic loading of libraries (DynaLoader, XSLoader)
also seems to have become broken in in SunOS 4.x. Therefore the default
is to build Perl statically.
Running the test suite in SunOS 4.1 is a bit tricky since the
F<dist/Tie-File/t/09_gen_rs.t> test hangs (subtest #51, FWIW) for some

GSM0338 is for GSM handsets. Though it shares alphanumerals with ASCII,
control character ranges and other parts are mapped very differently,
mainly to store Greek characters. There are also escape sequences
(starting with 0x1B) to cover e.g. the Euro sign.
This was once handled by L<Encode::Bytes> but because of all those
unusual specifications, Encode 2.20 has relocated the support to
this module.
This module implements only I<GSM 7 bit Default Alphabet> and
I<GSM 7 bit default alphabet extension table> according to standard
3GPP TS 23.038 version 16. Therefore I<National Language Single Shift>
and I<National Language Locking Shift> are not implemented nor supported.

ext/DynaLoader/DynaLoader_pm.PL view on Meta::CPAN
If it is defined and perl is compiled with the C macro C<DL_UNLOAD_ALL_AT_EXIT>
defined, then it is called automatically when the interpreter exits for
every shared object or library loaded by DynaLoader::bootstrap. All such
library references are stored in @dl_librefs by DynaLoader::Bootstrap as it
loads the libraries. The files are unloaded in last-in, first-out order.
This unloading is usually necessary when embedding a shared-object perl (e.g.
one configured with -Duseshrplib) within a larger application, and the perl
interpreter is created and destroyed several times within the lifetime of the
application. In this case it is possible that the system dynamic linker will
unload and then subsequently reload the shared libperl without relocating any
references to it from any files DynaLoaded by the previous incarnation of the
interpreter. As a result, any shared objects opened by DynaLoader may point to
a now invalid 'ghost' of the libperl shared object, causing apparently random
memory corruption and crashes. This behaviour is most commonly seen when using
Apache and mod_perl built with the APXS mechanism.

Pod::Html::Util - helper functions for Pod-Html
=head1 SUBROUTINES
B<Note:> While these functions are importable on request from
F<Pod::Html::Util>, they are specifically intended for use within (a) the
F<Pod-Html> distribution (modules and test programs) shipped as part of the
Perl 5 core and (b) other parts of the core such as the F<installhtml>
program. These functions may be modified or relocated within the core
distribution -- or removed entirely therefrom -- as the core's needs evolve.
Hence, you should not rely on these functions in situations other than those
just described.
=cut
=head2 C<process_command_line()>
Process command-line switches (options). Returns a reference to a hash. Will
provide usage message if C<--help> switch is present or if parameters are
