Ah, makes sense; sorry I did not ask to include me in CC explicitly.

Yes, I've just committed update to 1.7.9-jumbo-5 (I currently maintain the
port). Also I indeed "patch" src/Makefile with sed(1) to uncomment relevant
OMPFLAGS; I will see if I can pass it via MAKE_ARGS instead. I know that
you're generally against patching makefiles and param.h and fully support
you here. Maybe you can take a look at what it currently looks like and
suggest what can/should be improved.

No, of course not. It's a Dothan chip; I did not imply that building
OMP-enabled JtR would make sense on it, but I needed to test the build on
ia32 nonetheless.

OK, I will try to carry out some tests when my time permits and post them
here.
Thanks for the feedback, much appreciated!
