[Bug target/15037] New: -ffreestanding not taken into account when compiling main()

[xtrochu at yahoo dot com]

When compiling a function called "main" with gcc under mingw32, a call to __main
() is inserted before anything else. This is normal and expected.

The problem is that the same behaviour occurs when using the -ffreestanding 
compiler flag.

Step to reproduce :
$ echo "int main() { return 0;" > test.c
$ gcc -ffreestanding -S -o test.S test.c
$ grep "call" test.S
        call    __alloca
        call    ___main
$ gcc -v

the cygwin compiler (gcc version 3.3.1 (cygming special)) has the same behavior.
