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).

Regards,

Fabrice
