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). -- Stephane
