 I'm on Big Sur (11.4) with Xcode 12.5.1:
 {{{

 `config.log` says:
 {{{

 }}}
 ...so IOW it looks like another victim of `-Werror=implicit-function-
 declaration` being on by default now. Looking at the m4 macros in this
 port's source, it looks like it uses macros from neon, and the neon port
 had a similar bug (bug #61483), so the fix for that one could probably be
 brought over to this one.
