#46968: opusfile @0.6 does not build on 10.5.8

Component:  ports   |    Version:  2.3.3
 Keywords:          |       Port:  opusfile
--------------------+--------------------------------
 On MacOSX 10.5.8, audio/opusfile does not build,
 because this version of MacOSX does not have AI_NUMERICSERV defined,
 and src/http.c fails to compile.

 {{{
 :info:build src/http.c: In function 'op_resolve':
 :info:build src/http.c:725: error: 'AI_NUMERICSERV' undeclared (first use
 in this function)
 }}}

 It appears exactly once:

 {{{
 #if !defined(_WIN32)
   hints.ai_flags=AI_NUMERICSERV;
 #endif
 }}}

 What's the right thing to do here?
 Can we just drop these three lines on older darwins?

 (Does someone know when exactly AI_NUMERICSERV
 became #defined in MacOSX's netdb.h?)

 Another solution is to just --disable-http
 for the appropriate darwin versions,
 which seems like overkill.
