this works for me, thanks for the quick patch!

here i have problems. some tests fail more or less randomly.
after some testing, i found that it seems to be related to
the parsing of float literals in python code (wild guess).
for example, test_pow failed giving me this traceback:
Traceback (most recent call last):
", line 109, in test_bug705231
eq(pow(a, 1.23e167), 1.0)
AssertionError: -1.0 != 1.0
this seems very strange to me, as i get this on the interactive
>>> pow(-1.0, 1.23e167)
another example is test_colorsys. this test hangs, because it
uses "frange(0.0, 1.0, 0.2)" (which does, what it looks like),
but the 0.2 is somehow read as 0.0 resulting in an infinite
i have no clue whether these failures are related to my build
environment or something in the python codebase (or the weather?).
all tests passed when building with gcc from cygwin btw. i will
try building 2.4.2 with nant later and see what that does...
i am lost at the moment, David.
PS: maybe i should note: i built python without _bsddb and without
_tcl but i don't think this should be causing problems.
