[SciPy-user] problem building svn scipy

[Damian Eads]

Hi there,

The hierarchy_wrap.c file is code I wrote and Chris Burns checked in. I 
did not try to compile it with an earlier version of gcc. Sorry about that.

$ gcc --version
gcc (GCC) 4.1.2 20070925 (Red Hat 4.1.2-33)
$

I will log-in to a machine with gcc-3.4.1 and try recompiling. I hope to 
have a fix soon.

Robert: interesting catch. I could try renaming CS, _X, and _dm. Let me 
try reproducing this compiler error on a machine with the gcc version 
John is using.

It looks like something is #defining CS to be a number. Search through
the headers for this.

Possibly the same thing with _X or _dm. Are there any more errors
following this?
