This is what I get also with
Python 2.1.2 (#1, Jan 18 2002, 18:05:45)
[GCC 2.95.4 (Debian prerelease)] on linux2
and
Python 2.2 (#1, Jan 8 2002, 01:13:32)
[GCC 2.95.4 20011006 (Debian prerelease)] on linux2
but not with
Python 2.2 (#7, Jan 28 2002, 13:08:12)
[GCC 3.0.3] on linux2
Note the difference in GCC versions. Also gcc-3.0.3 is run on Suse linux.
Ok, I'll try first fix one f2py bug and then come back to linalg2.
Eric, do you have complaints about system_info on Win32?
