Yes, that is true, but most production systems run even older
versions, and I want a patch that works on those versions. I am now
building packages for Debian lenny (gcc 4.3.2) and Redhat 5 (even
older). I see this patch as a work around that gives me time for the
next step.

The next step is to upgrade to that latest GCC and the latest GC and
the latest Lucene and have that running on Debian Testing.
I will be looking into getting USE_MMAP to work, as I think that would
be a more definite solution. However if I enable it, it segvs.
Are there any specific obstacles for USE_MUNMAP when used in GCJ, or
should it just work?
