[issue9742] Python 2.7: math module fails to build on Solaris 9

Mark Dickinson added the comment: Matt: thanks for testing. Patch applied---this should be fixed now. I'm a little bit nervous about this one, since it may introduce new failures on systems with a buggy round implementation (Linux / alpha, for example). Still, we have tests for that, so I'l

Mark Dickinson added the comment: Looking back at the discussion, I think I got this bit wrong: "the round function is needed, and used, in Objects/floatobject.c (that is, if PY_NO_SHORT_FLOAT_REPR is *not* defined;" In fact, the round function is used if PY_NO_SHORT_FLOAT_REPR *is* defined, a
