MinGW using wrong as?

Hi,

I tried to use MinGW to cross compile a simple test program for windows on linux. (If you really want to see it, here it is:

#include <stdio.h>

int main()
{
  printf("hello!\n");
}

)

I tried running

i486-mingw-gcc test.c

, but it spits out (with verbose):

Using built-in specs.

In the output above I saw the line

 as -o /tmp/cc8WKGhw.o /tmp/ccRkIP7L.s

from which I think it's using the wrong 'as' (it should use i486-mingw32-as, not just as).

Is it a bug, or am I doing something wrong?

Thanks.
