    "global" variable G._wsize [Chr. Spieler]
 - unzpriv.h: use fputs() instead of fprintf() as output function in the
    FUNZIP variant of the Info() macro, to prevent misinterpreting format
    specifiers in the sprintf() output. [Martin Pitt, ubuntu]
 - unix/unix.c: added detailed compiler version info for SunPro cc, HP cc,
    DEC cc. [Steven M. Schweda]
 - vms/descrip.mms: added support for architecture detection macro symbols
    built into newer versions of MMK (a MMS clone).  [Steven M. Schweda]
 - fileio.c - is_vms_varlen_txt(): commented out the currently unused code for
    determining the VMS fileorg setting. [Steven M. Schweda]
 - extract.c - extract_or_test_files(): the "back at endsig" checking code
    is not used for the SFX stub. [Steven M. Schweda]
 - win32: changed all Win32-API calls with string parameters to explicitely use
    the ANSI variant; this removes the dependency on the UNICODE and _UNICODE
    compile flags being undefined.  [NN, Chr. Spieler]
 - zipinfo.c: on WIN32, archive filename display must be fed through codepage
    translation. [Chr. Spieler]
 - zipinfo.c - zipinfo(): repaired several memory leaks when the listing loop
    is stopped prematurely because of inner errors. [Chr. Spieler]
 - crc32.c, crc32.h, crc_i386.S, crc_i386.asm, crc_i386.c: comprehensive
    revision of crc32 calculation, implementing the optimized algorithms from

    Begin main loop over blocks of member files.  We know the entire central
    directory is on this disk:  we would not have any of this information un-
    less the end-of-central-directory record was on this disk, and we would
    not have gotten to this routine unless this is also the disk on which
    the central directory starts.  In practice, this had better be the ONLY
    disk in the archive, but we'll add multi-disk support soon.
