ExitProcess does not work in Cygwin?
$ rm *.exe
# u is for Unix
# w is for Windows
$ cat u.c
#include <stdlib.h>
int main()
{
 exit(1);
}
$ gcc u.c
$ ./a.exe
$ echo $?
1
 => as expected
$ cat w.c
#include <windows.h>
int main()
{
 ExitProcess(1);
}
$ gcc w.c
$ ./a.exe
$ echo $?
0
 => not expected
$ uname -a
