Hi Clemens,

I am trying to port the OpenJDK to Linux/SPARC first and Linux/MIPS
after that. Is it necessary to have gcc 3.3.6 in order to compile the Motif
portion of OpenJDK or can it be fixed to compile on gcc 4.1.2 as well?

You can try installing an older distribution in a virtual machine and
building gcc 3.3.6 inside it. Then you can transfer the packages to
your normal system. I have done this on my own system running
Slackware 12.0 and building gcc 3.4.6 on Slackware 11.0.
