gcc internal compiler error during compile of MySQL 3.22.27

[Robert Benites <benites at cs dot unca dot edu>]

Operating System: Compaq Tru64 (aka Digital) UNIX 4.0F with patch kit
                  #1 installed

gcc: 2.95.2 with dec-osf-shlibstdc++.patch installed
     gcc configured with the following command:
      ../gcc-2.95.2/configure --enable-shared
--enable-languages="c++,f77"

The error output at the end of this message was received during a
compile
of mysql-3.22.27. MySQL was configured with the following command:

env CC="cc -pthread" CFLAGS=-I./include CXX=gcc CXXFLAGS=-O3 ./configure
\
   --with-low-memory --with-named-thread-libs="-lpthread -lmach -lexc"

The above configure was used to create a running instance of MySQL on
another system: Compaq Tru64 UNIX 4.0E with the following version
of gcc:

Reading specs from /usr/local/lib/gcc-lib/alpha-dec-osf4.0a/2.8.1/specs
gcc version 2.8.1

Thanks!
