I am getting compilation error when I try to use the GNU ld's -O option:

`--> cat test.c
int
main ()
{
    return 0;
}

`--> gcc -Wl,-O -o test test.c
/usr/lib/gcc/x86_64-pc-cygwin/4.8.1/../../../../lib/libcygwin.a(libcmain.o):
In function `main':
/usr/src/debug/cygwin-1.7.24-1/winsup/cygwin/lib/libcmain.c:39:
undefined reference to `WinMain'
/usr/src/debug/cygwin-1.7.24-1/winsup/cygwin/lib/libcmain.c:39:(.text.startup+0x7e):
