Ok, I've just tried.  There are both C99 and non-C99 extensions,
and while I see there are replacement header files for some of
them, I can't even just copy those header files as a replacement 
since they have @ characters in them, which presumably needs 
to be processed by something else.

It would be nice if M4 compiled by default on a C89 compiler and
if the extensions are there for cosmetic or any other purpose,
that's fine, but the user needs to enable the use of those
extensions.

Since I'm not actually using m4 for any purpose on the mainframe,
and even if I was, the 1.4 version probably works fine, I'll just stick
with the back-level, unless there's an interim version before the
switch to C99 extensions.  I've included what I got up to before
being forced to use a stdbool.

BFN.  Paul.
