Which doc states that this is required ?

Fri May 15 10:04:27 1998 Marcus Meissner <marcus@jet.franken.de> * [configure.in][inlcude/acconfig.h] Fixed broken OSS check, added check for working sigaltstack, fixed broken statfs checks on some linux systems. * [files/directory.c][loader/pe_image.c][relay32/builtin.c] [loader/module.c] Added handling of win32 module pathnames. * [relay32/wnaspi32.spec] New file. * [misc/lzexpand.c] LZCopy auto-decompresses LZ compressed files, even if they are not specially flagged. Fixes some InstallShield problems. * [misc/registry.c] Some fixes for RegQueryInfoKey (reference program monkey.exe from Win32 SDK works now better). Probably still has faults.

Tue May 12 22:54:03 1998 Michael Mess <michael@kawo2.rwth-aachen.de> * [multimedia/audio.c] ioctl's do not commute in /dev/dsp initialization. Tue May 12 20:11:42 1998 Karl Garrison <karlos@eznet.net> * [win32/console.c] Implemented SetConsoleTextAttribute, FillConsoleOutputCharacter. Improved cursor positioning. This allows for text colors in an xterm, rxvt, or console. Tue May 12 17:57:52 1998 Petter Reinholdtsen <pere@td.org.uit.no> * [Makefile.in] Create prefix/{bin|lib} directories if missing during install.

Lukyanov <lav@long.yar.ru> * [misc/lstr.c] FormatMessage: terminate string on %0, undo linefeed strip.
