	Ah - indeed, there should be an autogen.lastrun.bak these days - but,
yes that's annoying :-)

	So this looks like it would work well, but it substantially duplicates
the functionality of ./configure --help - and maintaining that stuff in
two places sounds like work :-)

	I wonder if instead it would be better to special case '--help' in
autogen.sh so that if it is detected we don't write it to
autogen.lastrun.

	How does that sound ?

	Thanks !
