Comment (by kencu):

 OK, it look like the issue is here in

 {{{
 mesonbuild/compilers/objc.py
 }}}

 they have (incorrectly I believe) excluded gnu89 from the available
 options for the C std.

 If we can verify somehow to them that gnu89 should be an accepted option
 for Obj-C, then perhaps they can add it.

 Or we can patch it in as an accepted option ourselves, as it was
 (apparently) previously accepted.

 {{{
     def get_options(self) -> 'coredata.KeyedOptionDictType':
         opts = super().get_options()
         opts.update({
             OptionKey('std', machine=self.for_machine, lang='c'):
 coredata.UserComboOption(
                 'C language standard to use',
                 ['none', 'c89', 'c99', 'c11', 'c17', 'gnu99', 'gnu11'],
                 'none',
             )
         })
         return opts
 }}}
