Modify mingw_main() workaround to avoid link errors

With MinGW's

   gcc.exe (GCC) 3.4.5 (mingw special)
   GNU ld version 2.17.50 20060824

the old define caused link errors:

   git.o: In function `main':
   C:/msysgit/git/git.c:500: undefined reference to `mingw_main'
   collect2: ld returned 1 exit status

The modified define works.
