Well, they're tied to the C runtime library and I also just checked MSVC 2003 and it also shows _get_osfhandle() returning an intptr_t. The issue is whether anyone still compiles libtiff in older MSVC versions (ie. version 6 or lower). Hmm, I just checked a somewhat old distribution of MinGW (32-bit) and that has _get_osfhandle() returning a long. I'll keep that in mind. -Edward
