So the configure test for tanh(-0.0) is purely informational: it doesn't
affect the behaviour of the built Python in any way. I agree that the
test is imperfect, in that if atan2 is also non-conformant on the given
platform then the sign issue with tanh may go undetected, but all that
happens in that case is that we get a bogus 'preserves sign of -0 ... yes'
message in the configure output.
The wrapper for atan2 in Modules/mathmodules.c is a separate issue; it
should ensure that we get the right behaviour for atan2 on all platforms,
including msvc 7.0. I can't immediately see any reason why it wouldn't be
working as intended.
> I don't think that python cmath tests will pass with MSVC before
8.0.
Which test(s) do you think will fail?
> May be is good to add depends=['_math.h'], for modules in setup.py.
Good point---thanks! Done in r76865 (trunk), r76867 (py3k).
