Mac OSX Upkeep.

* configure: (need_svid_source, need_bsd_source): Variables removed.
(need_darwin_c_source): New variable. Detect Apple environment and add
-D_DARWIN_C_SOURCE, which is needed to reveal some functions in headers.

* signal.c (sig_init): Wrap #ifdefs around SIGPOLL; it is not defined
on Darwin.
