[bug #27809] several win64 fixes

[Eli Zaretskii]

Follow-up Comment #1, bug #27809 (project make):

Thank you for your contribution.  I have a few questions for the patches you
sent:

1. What versions of GCC and of MinGW runtime did you use to build Make?

2. Which header defines pid_t as appropriate for both 32-bit and 64-bit
Windows?  What is the definition for each one of them?

3. Why did you need casts in assignments, like this:

-    *pid_p = (int) hProcess;
+    *pid_p = (pid_t) hProcess;

Didn't it work without a cast?  (There are quite a few such casts; please see
which ones are absolutely necessary.)

4. This change:

-  pipedes[0] = _open_osfhandle((long) hChildOutRd, O_RDONLY);
+  pipedes[0] = _open_osfhandle((intptr_t) hChildOutRd, O_RDONLY);

assumes that _open_osfhandle accepts an intptr_t type as its first argument. 
But the prototype I have on my machine (in io.h) says the first argument is a
`long'.  Which version of MinGW changed that?

5. Finally, could you please see if the build_w32.bat script works for a
64-bit MinGW GCC?  If you see problems there, please report them.

Thanks.
