Ok, we're both in agreement here :-)

Hmm....I could split runetype.h into 2 files and provide one as an exposed
one to /usr/include which just contains the locale and file locale structs.
But, these are tied together with libc and there's no way around that...

The libc routines need the same structs to read the binary data back from the
files. Nothing else except mklocale really needs this information since the
binary files are essentially opaque types otherwise. Keeping separate includes
(one locally in mklocale) makes no sense since changes would cause divergence.

I'm open to ideas here but "rewrite mklocale to not use the libc stuff" isn't
gonna work. They are tied together and other programs do thing similarly when
needed (at first pass setkey in sbin pulls in includes from libipsec for
