/*
Unresolved issues Uwe Bonnes 970904:
- Handling of Binary/Text Files is crude. If in doubt, use fromdos or recode
- Arguments in crtdll.spec for functions with double argument
- system-call calls another wine process, but without debugging arguments
              and uses the first wine executable in the path
- tested with ftp://ftp.remcomp.com/pub/remcomp/lcc-win32.zip, a C-Compiler
 		for Win32, based on lcc, from Jacob Navia
AJ 990101:
- needs a proper stdio emulation based on Win32 file handles
- should set CRTDLL errno from GetLastError() in every function
*/

/* NOTE: This file also implements the wcs* functions. They _ARE_ in 
 * the newer Linux libcs, but use 4 byte wide characters, so are unusable,
 * since we need 2 byte wide characters. - Marcus Meissner, 981031
