Comment (by ecronin@…):

 The right fix is probably to make those functions 'static inline' since
 they're defined in .c files (and it isn't clang being fussy, it's -std=c99
 vs -std=c89).  However the Portfile also already blacklists *clang* as a
 workaround, so I'm not sure why you're hitting this.  Did you remove that
 blacklist?

 This is a dup of #41498 (except the blacklisting was supposed to force
 gcc), I'll fix the inlines and un-blacklist clang and then set
 maintainership to Craig like we discussed in that ticket but never acted
 on.
