Hmmm.  But, since most (all?) 'make' commands only do time-stamp
checking to determine if a target should be rebuilt, if the rerun of
configure causes the Makefile(s) to be regen'ed with new or changed
commands in a target, that target may not be rebuilt because you
didn't "clean" your environment first.  True?

When you're familiar with the environment (as you are with Emacs), you
can get away without cleaning your environment first.  However, the
safe approach is to only 'configure' in a clean environment.

CPU cycles are relatively cheap nowadays...  ;-)
