Hi,
I've tried to reproduce, but failed:
a.c: #include <stdio.h> #include <stdlib.h>
int main(void) { system("qqq.exe"); return 0; }
$ mingw-gcc -mconsole -mno-cygwin a.c $ wine a.exe
It works.
$ mingw-gcc a.c $ wine a.exe
It works too.
Executable qqq.exe exists in ~/.wine/drive_c/windows directory.
