Added PyErr_WarnPy3k function. (issue 2671) I will be converting current Py3k warnings to the use of this function soon.

the compiler.  This should(?) help to fix failures in test_math
and test_cmath on Linux/alpha.

Also add configure message reporting the result of uname -m, as
a debugging aid.

This is a modified version of a patch proposed by Humberto Diogenes

This causes IDLE to crash when too many warnings are printed.

Will backport.

apparently because tanh(-0.) loses the sign of zero on that platform.
If true, this is a bug in FreeBSD.

Added a configure test to verify this.  I still need to figure out
how best to deal with this failure.

a warning instead of failing with a termios.error.
