Hi Matthew,

RedHat 5.2 comes with glibc 2.0.7 and RedHat 6.0 comes with a
prerelease of glibc 2.1.1.  If your program works on 5.2 it should
work on 6.0 also.

I guess the problem is not glibc but your installation.  For example
<DLList.h> is part of libg++ - is this installed?  Check first that
you've got the development version of all packages
(glibc,c++,libstdc++,libg++).

Btw. gcc has a number of debugging flags which might be helpful.
Check -E for preprocessed output, -v for verbose output and
-Wl,--verbose for details of the linking stage.

If you've still got a problem, please provide more details.  Tell us
exactly what you're doing.  If you don't get it working, you might ask
RedHat.

Andreas
