- Reenable modules on x64 that had been disabled aeons ago for Itanium.
- Cleared up confusion about compilers for 64 bit windows. There is only Itanium and x64. Added macros MS_WINI64 and MS_WINX64 for those rare cases where it matters, such as the disabling of modules above.
- Set target platform (_WIN32_WINNT and WINVER) to 0x0501 (XP) for x64, and 0x0400 (NT 4.0) otherwise, which are the targeted minimum platforms.
- Fixed thread_nt.h. The emulated InterlockedCompareExchange function didn´t work on x64, probaby due to the lack of a "volatile" specifier. Anyway, win95 is no longer a target platform.
- Itertools module used wrong constant to check for overflow in count()
- PyInt_AsSsize_t couldn't deal with attribute error when accessing the __long__ member.
- PyLong_FromSsize_t() incorrectly specified that the operand were unsigned.
With these changes, the x64 passes the testsuite, for those modules present.
today. pyconfig.h can override it if not, and can also override
Py_IS_INFINITY now. Py_IS_NAN and Py_IS_INFINITY are overridden now
for Microsoft compilers, using efficient MS-specific spellings.
This changes sys.version under Microsoft builds to include the MS compiler
version number (_MSC_VER). Since VC 6 and VC 7 are apparently
incompatible, and both can be installed on a single box, distutils needs
some way to figure out which version of MSVC a given Python was compiled
under.
As also suggested by MvL, got rid of #ifdef'ery for the defunct _M_ALPHA
target.
Bugfix candidate? Hard to say. As far as I'm concerned, VC 7 wasn't
a supported platform in the 2.2 line. If somebody thinks it should be,
they can do the work.
Removed "#undef HAVE_HYPOT" line from Borland config, as suggested.
Whether this will break some other Borland usage is a good question I
can't answer.
Curious: the MS docs say stati64 etc are supported even on Win95, but
Win95 doesn't support a filesystem that allows partitions > 2 Gb.
test_largefile: This was opening its test file in text mode. I have no
idea how that worked under Win64, but it sure needs binary mode on Win98.
BTW, on Win98 test_largefile runs quickly (under a second).
