* Default to using /dev/tty for the password prompt and input before
  falling back to sys.stdin and sys.stderr.
* Use sys.stderr instead of sys.stdout.
* print the 'password may be echoed' warning to stream used to display
  the prompt rather than always sys.stderr.
* warn() with GetPassWarning when input may be echoed.

work.  (The test wasn't properly linked with libm.  Sigh.)

It seems to work, but will fail at the first flush.

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.

should fix the problem in the same way that
the cmath.phase problems were fixed.

info for all processed zip files, even when they are no longer used.

the phase and polar methods.

cmath module is loaded) instead of statically. This fixes compile-time
problems on platforms where HUGE_VAL is an extern variable rather than
a constant.

Thanks Hirokazu Yamamoto for the patch.

math.pow behave on alpha Tru64.  All IEEE 754
special values are now handled directly; only
the finite**finite case is handled by libm.

special-value handling to math.modf code.

test_math, to help track down debian-alpha
buildbot failure.

Remove meaningless 'in radians' from inverse
hyperbolic functions.

0**nan is nan, not 0.  (But nan**0 and 1**nan are 1.)

Also fix minor typo: 'quite NaN' -> 'quiet NaN'

Windows/VS2008 doesn't like (-1)**(+-inf).

handling code in math.pow, in the hope of making all
tests pass on the alpha Tru64 buildbot.
