To add on that, the code was removed at some point altogether
http://git.savannah.gnu.org/cgit/emacs.git/commit/?id=58eb6cf0f77547d29f4fddca922eb6f98c0ffb28
in emacs-24.0.96 and then added back without the #ifdef
BSD_PGRPS
http://git.savannah.gnu.org/cgit/emacs.git/commit/?id=322aea6ddf7ec7fd71410d98ec1de69f219aff3e
in emacs-24.2.90

So versions 24.0.96 to 24.2 must have been broken under
gnu-linux as well, and newer versions (24.2.90 and above) should
be OK including on FreeBSD|OS/X (so no need to report it as a
bug to the emacs maintainers).
