GnuWin

You shouldn't include the glibc headers directly, but use the patched mingw
headers, as described on the LibGw32C page. Also, compile with -D__GW32__

1) Yes. On any MS-Windows system, fork has to be replaced by a series of
statements involving CreateProcess; see
http://msdn.microsoft.com/library/en-us/dnucmg/html/UCMGch09.asp?frame=true#ucmgch09_topic8
http://msdn.microsoft.com/library/en-us/dnucmg/html/UCMGch09.asp?frame=true#ucmgch09_topic13e
http://msdn.microsoft.com/library/en-us/dnucmg/html/UCMGch09.asp?frame=true#ucmgch09_topic13f
2) What are 'backticks'?
3) Pipe is implemented with system or CreateProcess.
4) No.

Onderwerp: [GnuWin32-Users] Cannot fork...
