Unfortunately, every Linux platform I've ever seen is infected with a
gcj install.  So I'd like to find out how to work around it, rather
than trying to eradicate it.

Yeah, except that I don't want to devote my life to finding out how to
be a sysadmin on all the various flavors of Linux.  I'd rather have
JCC control the build environment so that the bad gcj headers and/or
libraries don't get accidentally found.

Sure enough, that's the difference.  Adding "--package java.lang" to
the "python -m jcc" line, as PyLucene does, somehow changes the gcc
command line, and things compile.
