Allow Gnu gcc's to build python on OSX by removing -Wno-long-double,
-no-cpp-precomp, and -mno-fused-madd from configure. * r22183 added -no-cpp-precomp, which http://gcc.gnu.org/ml/gcc/2005-12/msg00368.html claims hasn't been needed since gcc-3.1. * r25607 added -Wno-long-double to avoid a warning in Include/objimpl.h (issue 525481). The long double is still there, but OSX 10.4's gcc no longer warns about it. * r33666 fixed issue 775892 on OSX 10.3 by adding -mno-fused-madd, which changed the sign of some float 0s. Tim Peters said it wasn't a real issue anyway, and it no longer causes test failures. Fixes issue #1779871.

-----------------
|

|

- Issue #1779871: Gnu gcc can now build Python on OS X because the
|
||||
flags -Wno-long-double, -no-cpp-precomp, and -mno-fused-madd are no
|
||||
longer passed.
|
||||
|
||||
- Add a warning when asserting a non-empty tuple which is always true.
|

- Issue #2179: speed up with statement execution by storing the exit method
