I can't remember one.  One thing to know is that automake's generation, especially in the early days, was heavily
influenced by a small group of GNU hackers (the infamous "gnits"
group).  These heroes maintained a number of GNU packages and
collaborated on decisions regarding the interpretation and
implementation of the GNU Coding Standards.  Some of the code automake
generates still dates from that era.  It is possible that this
renaming dates to then.  Of course, it is also possible that this
renaming was done by me just to make the dejagnu stuff a bit simpler.
I really don't remember.

Unfortunately these variables are documented.  So we need to continue
supporting these names for a while.  Bonus points if you can make a
patch that warns about the use of an obsolete macro name in

Beyond that I think changing them to reflect autoconf is a good idea.
