bdiff: convert more longs to int64_t MSVC previously flagged these where the function is stored in a pointer: bdiff.c(284) : warning C4028: formal parameter 1 different from declaration bdiff.c(284) : warning C4028: formal parameter 2 different from declaration bdiff.c(284) : warning C4028: formal parameter 3 different from declaration bdiff.c(284) : warning C4028: formal parameter 4 different from declaration

xdiff: silence a 32-bit shift warning on Windows It's probably harmless, but: warning C4334: '<<' : result of 32-bit shift implicitly converted to 64 bits (was 64-bit shift intended?) Adding a 'ULL' suffix to 1 also works, but I doubt that's portable.

xdiff: backport int64_t and uint64_t types to Windows Sadly, MSVC 2008 lacks stdint.h. These are the only two definitions needed right now.
