  12 Unresolved issues Uwe Bonnes 970904:
  13 - Handling of Binary/Text Files is crude. If in doubt, use fromdos or recode
  14 - Arguments in crtdll.spec for functions with double argument
  15 - system-call calls another wine process, but without debugging arguments
  16               and uses the first wine executable in the path
  17 - tested with ftp://ftp.remcomp.com/pub/remcomp/lcc-win32.zip, a C-Compiler
  18                 for Win32, based on lcc, from Jacob Navia
  19 AJ 990101:
  20 - needs a proper stdio emulation based on Win32 file handles
  21 - should set CRTDLL errno from GetLastError() in every function
  22 UB 000416:
  23 - probably not thread safe
