Straight over the top of my head yesterday :)  Is the following 
what you had in mind?  (current script does retry if BROKEN)

grant@sempro:/opt/linux$ diff -u linux-2.6.13-rc3-git6/init/Kconfig~ linux-2.6.13-rc3-git6/init/Kconfig

Here http://scatter.mine.nu/test/scripts/counterror-2005-07-26.gz
is post-processing script (work in progress) extracts errors and 
non-deprecated warnings, linked to first triggering .config like so:

grant@sempro:/opt/linux$ cat error-error-list

trial1/run-015:net/rxrpc/main.c
trial2/run-027:sound/core/memalloc.c

then extracts compiler messages:

Datastore is denormalised flat text.  Query language: grep :)
