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
