BTW I tried this suggestiong but found that AC_CONFIG_HEADERS doesn't solve
the problem at hand.. I still get:

Making all in include
cd .. && /bin/sh /home/mjl/dev/plplot/latest/missing --run autoheader

I think there are still a lot of outstanding issues.

This stuff is mostly orthogonal to the stuff I was looking at, which included:
 - support for --with-warn,  --with-profile, etc
 - better support for non-GNU compilers (e.g. KCC)
 - separation of internal-use-only configuration info from headers exported to
   the public namespace
 - proper include guards for headers

The latter one does overlap with the plConfig.h / plDevs.h problem tho.

I really have no idea when I'm going to be able to work on any of that, as I
have features work to do and can hack my way around the config issues for now.

Yes.
