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).
