Summary: Random on PPC is outside acceptable range.

Initial Comment:
On LinuxPPC, with gcc 2.96, python's (2.2.2) random function is outside the acceptable range. For example:

>>> import random
>>> print random.random()
1.35933812391

This random function, I believe, is supposed to produce numbers between 0 and 1.

What does the following statement print under this Python:

print 1.35933812391 % 1,.0

?

Note that there's almost no chance this is a bug in Python 
(the implementation of random() hasn't changed in about 10 
years).  There's a good chance it's a bug in the specific  C 
compiler or C library release you're using.
