I have tried this, CreateProcess doesn't find "cmd.exe" if we don't specify
the full path. (This happend in the test case with the neccessary changes
made to default to "cmd.exe"). But yes, it would be great.

But the question is whether or not CreateProcess _should_ find it, or not.
If it is, than it's a bug in CreateProcess, and working around it is rather
detrimental. If not, than fine, use the full path. We should always try
to fix the bug at the source, not to invent workarounds.

Jaco, did you make sure you have the correct link into
C:\windows\system32 created by wineinstall ?

lrwxrwxrwx    1 syl      wine           31 aoû  3 09:08
/home/c/windows/system32/cmd.exe -> /usr/local/lib/wine/wcmd.exe.so

Yes, it is correct. My A07 patch fixes this issue by calling "wcmd.exe" 
(without the hard-coded path) as per Francois's suggestion.
