And I was just going to delete my 2.95.3 compiler...

At one time, gcc 2.95.3 was required.  Since then, we have made changes so
that it compiles and runs with the latest gcc, but I don't believe we've
made any changes known to break 2.95.3 compatibility.  The reference in
the archives was to problems we had getting things to link and run with
early builds of Red Hat's 2.96 "interim" compiler.  At the time, the
clean gcc 2.95.3 was the fallback.  Later builds of the 2.96 compiler
worked with no problem.

The Osi unitTest using CLP compiles with no errors on my machine (Red Hat
Linux 9) but I haven't managed to get it to link to the older libraries.
Object files from 2.95.3 will reliably fail to link with the newer glibc
and libstdc++, but I doubt that will be a problem for you if you are
already using the old compiler and libraries.
