I'll check this patch again before the end of the week since we don't seem to be in a hurry.
All I can say for sure is that in several places the compiler (not gcc, but msvc)
inserted sign extent instructions. I tracked them down to mismatches between ints and intptr_t
or ptrdiff_t. I fixed them by removing all compiler warnings of this kind.
I also had to convert all DWORD uses for adresses to DWORD_PTR (MS recommended
way of dealing with 32/64 bits).
For the record and to make sure everyone is aware of it, compiling with msvc for x64, you get :
C:\Temp>long
short 2
int 4
long 4
long long 8
void* 8
The only difference with x86 is the size of the pointer which is 4 bytes (obviously).

gmalloc.c and ralloc.c must be exceptions from this rule, for obvious
reasons. (Though the 64-bit Windows build probably is, or will be,
the only 64-bit platform to use these two.)
I'd also take a very good look at all the EMACS_UINT uses, and a few
`long's and `unsigned long's in regex.c.
