Add AC_USE_SYSTEM_EXTENSIONS to expose non-standard extensions
Required on Solaris to expose fd_mask in <sys/select.h> now that xtrans 1.3 defines _XOPEN_SOURCE to 600 on Solaris, since fd_mask is not defined in that version of the XPG standards. Fixes build failure: os/connection.c: In function ‘CreateServerSockets’: os/connection.c:335:10: error: ‘fd_mask’ undeclared (first use in this function) os/connection.c:335:10: note: each undeclared identifier is reported only once for each function it appears in os/connection.c: In function ‘ListenWellKnownSockets’: os/connection.c:416:5: error: ‘fd_mask’ undeclared (first use in this function) os/connection.c: In function ‘EstablishNewConnections’: os/connection.c:562:5: error: ‘fd_mask’ undeclared (first use in this function) os/connection.c: In function ‘CloseDownFileDescriptor’: os/connection.c:684:10: error: ‘fd_mask’ undeclared (first use in this function) os/connection.c: In function ‘CheckConnections’: os/connection.c:701:5: error: unknown type name ‘fd_mask’ os/connection.c:711:17: error: ‘fd_mask’ undeclared (first use in this function) os/connection.c: In function ‘OnlyListenToOneClient’: os/connection.c:770:2: error: ‘fd_mask’ undeclared (first use in this function) os/connection.c: In function ‘ListenToAllClients’: os/connection.c:801:2: error: ‘fd_mask’ undeclared (first use in this function) Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Reviewed-by: Daniel Stone <daniel@fooishbar.org>
