At present frysk uses the path:
.java -> .o -> .a
to build its native code. This was forced by a number of problems with older
java compilers mis-compiling, mis-re-building, and/or messing up errors when the
more traditional .java -> .class route was taken. The .java -> .o route proved
far more robust.
Unfortunatly, now with Fedora 7++, the compiler is tuned more for the bulk
.java->.class route so switching to that will improve the F7 build experience.
On RHEL 4, just the ability to scratch build is needed.
