[Numpy-discussion] floating point exception weirdness

I hunted down the error and modified Doc/INSTALL.txt (patch below, 
please modify numarray sources) to indicate that the problem is not 
confined to Fedora Core1 but to any i386 linux with libc < 2.3.3 and 
SSE-using code.

With my newly patched and compiled libc, my system runs great, and no 
more mysterious Floating Point Exceptions!

Cheers!
Andrew
