The 2.44 changes to objimpl.h, especially the "long double" bit, causes numerous warnings on Mac OS X (and possible on other gcc-based platforms). Maybe the suggestion of adding the -Wno-long-double option should be taken, maybe something else should be done (adding a config-based define for the type with the biggest alignment requirement?).

/Users/jack/src/python/Include/objimpl.h:275: warning: use of `long double' type; its size may change in a future release
/Users/jack/src/python/Include/objimpl.h:275: warning: (Long double usage is reported only once for each file.
/Users/jack/src/python/Include/objimpl.h:275: warning: To disable this warning, use -Wno-long-double.)
