Even if you hit the same problem with 2.0.4, you should still better try
it with the latest available compiler (e.g. 2.0.4-rc2 or snapshot compiled
from the current SVN sources) and try to fix possibly existing issues in
that one (either directly yourself or by discussing with other people who
can provide more insight in the technical details) rather than trying to
create non-existing 2.0.2 SPARC compiler, because the problem might still
exist in 2.0.2, but could be e.g. resolved in 2.0.4 or the current 2.1.1
sources. Trying to fix the history usually doesn't work very well, you
know. ;-)
