Question :
is there any one of the supported platforms that dont support a 64 bit
integer
type. i'm not referring to the native int size.
for one i can think of Windows 95/98.

i'm porting a library and i need to know this so i can determine how to
proceed.

64 bit integer support is really a function of the compiler, not the OS.
The windows compiler certainly does support a 64 bit integer type (INT64
iirc).

There is probably a configure check somewhere (the bundled mysql client
library from 4.3 branch comes to mind) that you can use to make the decision
on 64 bit support.

my concern is not the configure check, per se. im just concerned that having
the
extension depend on 64bit support would eliminate a significant supported
platform.
as i current only have access to MSVC and gcc, i wanted to
do a quick shout to see if someone knew offhand which of the popular
compilers
would have an issue.

p.s.. its a largish codebase with 2 developers, so i wouldnt want to
simultanously
support a 64bit and a 32bit branch.

Maybe something like that could help you:

#define HAS_INT64_PRIMITIVE
#ifdef MSVC
#define int64_t __int64
#elif ...
#else
typedef struct int64_t_ { int32_t a, b; } int64_t;
#undef HAS_INT64_PRIMITIVE
#endif
