Subject: [PATCH] Submitted by:	Sascha Schumann <sascha@schumann.cx> Reviewed
 by:	Rasmus Lerdorf

    -   INADDR_NONE is not defined. Supply a replacement
    -   APACHE_MODULE() used a non-portable shell construct
    -   inet_addr() needs -lnsl -lsocket. Neccessary checks added
    -   For POSIX conformance, _POSIX_PTHREAD_SEMANTICS is
        required. This fixes i.e. sigwait() problems.
