Yes. I tested it with -mwindows -mno-cygwin. I couldn't print to the
console in that case so I ran it under the debugger.
I copied the WinMain from setup.exe into a test program.
cgf
#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
int WINAPI
WinMain (HINSTANCE h,
HINSTANCE hPrevInstance,
LPSTR command_line,
int cmd_show)
{
char **argv;
int i;
for (i = 0, argv = __argv; *argv; argv++)
printf ("%d - '%s'\n", i, *argv);
}
