True, but that's only a sketchy spec for the C language.  Huge chunks
of the language are omitted from the POSIX spec.  It's not at all an
adequate resource for C99 (or for C89, for that matter).

But that's fine!  That's what "configure" does on Unix-like hosts.
It's common for "configure" to "translate" .h files by renaming them,
copying them with small changes, etc.  I have no qualms about
suggesting this sort of thing for MVS as well.

MVS.  Gosh.  I haven't written serious JCL code for 30 years.  I used
to know JCL almost by heart, believe it or not!
