mimic older C90 behaviour.
.TP
.BI \-t
disable trigraph support; this seems to be required for some legacy code.
.TP

.TP
.BI \-wt

.TP
.BI \-zI
do not use the standard (compile-time) include path.

emit only the names of encountered files, separated by spaces; this is
intended for automatic generation of Makefile dependencies.

do the same as

but also for system files.

direct the ouput to
.I file
instead of standard output.

undefine
.I macro.

predefine system-dependant macros.
.TP
.BI \-Z
do not predefine special macros such as

to the list of assertions.
.TP
.BI \-B foo(bar)
remove
.I foo(bar)
of the list of assertions; you may also use
.BI \-B foo
to remove all
.BI \-B foo(xxx)
from the list of assertions.
.TP
.BI \-d
instead of normal output, emit '#define' directives representing all
macros defined during processing.
.TP
.BI \-e
instead of normal output, emit '#assert' directives representing all
assertions defined during processing.
.TP
.B Miscellaneous Options
.TP
.BI \-v
print version number, include path and (optionaly) defined assertions.
.TP
.BI \-h
print some help.
.SH ENVIRONMENT

library functions that might be affected, depending on the system.
