   I did not ask you to diagnose a correction!  You keep saying there
is something wrong.  Why do you say that?  Surely, your remarks are
based on something - some message, error events or something else.
With some description of that I might have some idea.

You are still using gcc 3.3.????? which was build on and for a RedHat
9 machine and you are now using the same binaries of the compiler on a
fedora core 2 system?  That alone might cause trouble.  You could
consider re-installing the compiler under your current OS.  But we
have had numerous reports of trouble under 3.3.3 and 3.3.4 - I use
3.2.3 with no problem - but under RedHat 9 (build for RH 9).
