Hum. Can you include the whole log from the last successfully compiled
file to the error? Odds are the warning appears somewhere up in the
log, but you can't see it because you're compiling in verbose mode and
other messages push it out of the screen. Redirecting output to a log
file (possibly using 2>&1 | tee foo.log) can help, too.

Problem is, ASDF doesn't know what warning was issued: all it gets is
a boolean result from compile-file. Gathering otherwise uncaught
warnings is not impossible, being a matter of some handler-bind
wrapper around compilation -- but it hasn't been done (yet) as part of
ASDF (we at ITA use something like that to do warning filtering,
though not warning summary; our latest code is included in the XCVB
driver).

This is not going to make it in ASDF 2.0 that I still intend to
release this Monday unchanged from 1.728. Definitely an ASDF 3.0
feature, though, maybe even 2.1.
