-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 According to Christopher Faylor on 1/12/2006 12:24 PM: > This particular application was ircd.

That is a bug in ircd. It is ircd's responsibility to define _POSIX_SOURCE itself if it wants strict POSIX compliance. In other words, if ircd wants to guarantee that it will compile on all POSIX-compliant systems, it should have defined _POSIX_SOURCE and then it could blindly use setsid() without any further heartburn. But it is possible to be portable to more systems than just those that are POSIX-compliant, so the better approach for ircd would have been to do an autoconf test for the existance of setsid, whether or not _POSIX_SOURCE was defined, and not a test for the existance of _POSIX_SOURCE. - -- Life is short - so eat dessert first!
