I see the following error when trying to build GnuPG 2.5.0 on macOS:

  exechelp-posix.c:527:5: error: use of undeclared identifier 'environ'
    environ = act->environ;
    ^
  1 error generated.
  make[3]: *** [libcommon_a-exechelp-posix.o] Error 1

Similar to the suggestion in https://dev.gnupg.org/T7169 , I was able to
temporarily work around the issue by creating a crude patch (attached).
