[SciPy-user] problem building svn scipy

[Damian Eads]

Hi,

I have compiled python 2.5 with gcc 3.4, as verified below.

[eads scipy]$ gcc --version
gcc34 (GCC) 3.4.6 20060404 (Red Hat 3.4.6-8)

[eads scipy]$ python
Python 2.5.2 (r252:60911, Apr 25 2008, 19:21:27)
[GCC 3.4.6 20060404 (Red Hat 3.4.6-8)] on linux2

[eads scipy]$

I checked out numpy and scipy from scratch and they build with gcc 3.4.6 
without error. I tried searching through the numpy and scipy headers for 
CS, _X, and _dm. I could not find any references to them. I then tried 
building numpy and scipy with gcc34-python 2.4, and they also built 
without error.
