I still have some #ifdef SVR4ARCHIVES in arch.c on OpenBSD, which more or
less should correspond to GNU long filenames. I've clenaed up the code 
somewhat, but I'm very certain I did not write it. So at some point, bmake
had support for those, and also for BSD style filenames.

That said, it's a feature that is only there to satisfy POSIX. I don't think
I've ever met an actual Makefile that uses it...
