#70267: libgpg-error @1.50 does not build: Undefined symbols: "_environ"
--------------------------+--------------------------
 Reporter:  barracuda156  |      Owner:  Schamschula
     Type:  defect        |     Status:  assigned
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.9.3
 Keywords:                |       Port:  libgpg-error
--------------------------+--------------------------
 The patch used in https://github.com/macports/macports-
 ports/commit/72a1a9efe3711c6dcfeb8bedc96fe837ef0fe7dd fails to work:

 {{{
 Undefined symbols:
   "_environ", referenced from:
       _environ$non_lazy_ptr in libgpg_error_la-spawn-posix.o
 ld: symbol(s) not found
 }}}

 Unfortunately, replacing it with what is usually correct:

 {{{
 #ifdef __APPLE__
 # include <crt_externs.h>
 # define environ (*_NSGetEnviron())
 #else
   extern char **environ;
 #endif
 }}}

 does not work here:
