I need to see a makefile which does this.

There's two issues here which I think you are confusing:

 1) Presently, rebuild-gcj-db and aot-compile-rpm _are_ alternatives,
    though not between JVMs: they're shared between versions of
    java-1.4.2-gcj*-compat.  Tom Fitzsimmons wants them not to be
    alternatives, but to be in gcc subpackages (libgcj for r-g-d, and
    gcc-java for a-c-r).  Almost incidentally, Tom pointed out that
    rebuild-gcj-db is so small its functionality could easily be
    incorporated in gcj-dbtool.

 2) On the other hand, Fernando wants the two scripts to remain
    alternatives, but shared between all JVMs (not just GCJ ones).  My
    opinion is that something like this would be a good idea, but that
    acquiring the GCJ-specific command names for it is the wrong thing
    to do (not least because GCJ's database should be rebuilt whenever
    an rpm with GCJ-precompiled stuff is installed regardless of what
    JVM alternative is in force).  This needs more discussion (on
    JPackage lists so the relevant people see it) but the result of
    that discussion should not stop us from making the GCJ-specific
    changes to the GCJ-specific rpms that we need for future
    development.

Cheers,
Gary
