I have a question regarding this patch:

  diff -u -p -r2.27 config.h.W32.template
  --- config.h.W32.template     25 Oct 2009 18:56:44 -0000      2.27
  +++ config.h.W32.template     5 Jul 2010 19:43:20 -0000
  @@ -426,7 +426,11 @@ this program.  If not, see <http://www.g
   /* Define to `int' if <sys/types.h> does not define. */
   /* GCC 4.x reportedly defines pid_t.  */
   #ifndef _PID_T_
  +#ifndef _WIN64
   #define pid_t int
  +#else
  +#define pid_t __int64
  +#endif
   #endif

Why is this needed?  Is there really a MinGW64 port of GCC whose
version is less than 4?  If MinGW64 only has GCC 4.x or later, it is
supposed to define pid_t in the header files supplied with GCC.
Please check.
