marcus and kris changed that lines a few times in the past, but
PTHREAD_CFLAGS never contained -pthread. The reason is that such
variable was intended for FreeBSD and no preprocessor flag is needed
since FreeBSD 5.

Yes, it could define other flags and it could link other libraries, but
actually it doesn't do it.

I agree with you that using -pthread on compiling and linking is The
Right Thing. My objection is that the porter's handbook says maintainers
*must* patch ports to use -pthread. When PTHREAD_CFLAGS/LIBS were added
to bsd.port.mk (and such requirements added to porter's handbook) there
was a specific actual reason and we should obey. Now there isn't
anymore, we can finally live happy and stop patching ports.

A more useful addition in the Porter's handbook IMHO would be an entry
about 'ltverhack' to avoid useless shared library bumps. Even this is
not mandatory, but at least we get a huge gain.
