gcc 2.95.2 fails on OSF 4.0f with internal error when compiling MySQL (C++ code)

Hi!

I am the MySQL maintainer and I am trying to do a binary distribution
of MySQL 3.23.6 on OSF1 4.0f

When compiling MySQL gcc 2.95.2 fails with:

shell> gcc -v --save-temps -DMYSQL_SERVER                      -DD

Note that this works on other OS/architectures)

After compiling the above file, without -O3 everything else in MySQL
compiles and the resulting executable passes a couple of simple test
suites.

I have included the ..ii file in the mail.  Mail me if you need
any further information.
