hmm... good question.  I realize that boehm-gc/Makefile has been
completely rewritten for automake; I wasn't taking that into account.

I'll try it again tonight.  I just noticed configure.in has a special
case for alpha:

case "$host" in
  alpha-*-*)
    machdep="alpha_mach_dep.lo"
    ;;

Since config.guess says my machine is "alphapca56-unknown-linux-gnu" I
guess it fails that test...

Yes.  I actually coded and tested it against 4.14.  I want to look over
the dynamic loading stuff though before I pass it along.

BTW I noticed some line-wrap in my patch... including it in the body of
my message is probably not such a great idea.  You can also fetch it
from http://people.sigma6.com/~jsturm/libgcj.patch.
