Well, I tried the above change (see CVS HEAD where I committed the change
for discussion purposes), but it didn't work, and I think Maurice has
just run into the same problem.  I assumed that all you had to
do above was mention plDevs.h, in AC_OUTPUT, and autoconf would take care of
the rest, but all it did was simply copy plDevs.h.in to plDevs.h, which of
course isn't what we want.

I believe a quick workaround for the original date problem that causes this
mess is to revert back configure.ac to what we had before and simply touch
include/plDevs.h.in right before bootstrap.sh is invoked and the tarball
created.  But I would much prefer this problem to be solved at a fundamental
level rather than with such a workaround which is bound to come back and
haunt us.

One question that springs to mind is why do we have all the device #define's
both in plConfig.h and PlDevs.h?  Could we just drop plDevs.h altogether (at
least for Linux/Unix systems) and use only plConfig.h?  That would require
some big but straightforward changes to our hierarchy of PLplot includes,
but I think it would work.

Alternatively, if we really want PlDevs.h created separately, then somebody
has to figure out the autoconf commands to process Pldevs.h.in into PlDevs.h
properly without using the AM_CONFIG_HEADER macro (which would run you into
the date problems which started this thread).
