you are right, this is incompatibility.
But I don't think this would be breaking any documented behaviour,
as I cannot find any place which says that AC_CHECK_PROGS caches its
result. In my quick search, I found only a note that "many checks"
cache their results.

If this is a real-life problem, that I really should add caching to
specific checks (AC_PROG_AWK and such).
If they rely on sharing ac_cv_prog_WEIRD, then I'd say they aren't
properly designed, and they will have to be fixed.

I think that config site should use something like
: ${AWK=gawk}
and not mess with the ac_cv_prog_AWK.
Have a nice day,
