Hmm, I would have thought configure would set up most of what you needed
below, but it's possible our autoconf is not very complete (unlike many
projects, it's not necessary to use it to build).

Rather than edit the Makefile, you can put these in "config.mak" which
is sourced automatically by the Makefile (after the defaults are set up,
so you can override them).

Great, I'm glad it's working. With NO_PTHREADS set, you will be
fork()ing off the sideband process instead of using a thread. So you
avoid pthreads altogether and it works, but you can't do multi-threaded
delta compression.

If you build without NO_PTHREADS set on a Solaris 9 box, does it work on
that same box? That would confirm or deny my ABI compatibility theory
(and hopefully point us in the right direction for the sunfreeware
people to build a binary that works on Solaris 9 and 10).
