You are right.  I investigated this issue more deeply and discovered that
Automake always include in include/Makefile.in a rule for rebuilding the
files defined in AC_CONFIG_HEADERS using autoheader.  For now, I did not
discover how to disable this.

Now, if the call to autoheader that you metion above only happens for
developper, that is okay, since it will be harmless.  What is very important
for us right now is to get a source tarball for which autoheader is not
called when users run configure/make.

Since you are reluctant to incorporate plDevs.h into plConfig.h (and I
understand your arguments), we must find a way to get the Autotools (in this
case Automake specifically) to behave correctly with two configuration
header files. 

One of the things that is strange now is that all the PLD_* #defines are
duplicated in plConfig.h.in and plDevs.h.in.  That is possibly a screw-up of
mine in the past.
