 Sure -- I use a script like this for regenerating all the scripts:

for name in `find . -name 'configure.[ai][cn]' -exec dirname "{}" \;`; do
	(cd $name && autoconf)
	STATUS=$?
	if [ $STATUS -ne 0 ]; then
		exit $STATUS
	fi
done

I have similar scripts for running `libtoolize', `aclocal', `autoheader' 
and `automake' if interested.  They should make the tree consistent, 
though configuring and running `make' may be necessary afterwards and 
before committing the changes for some timestamps to be updated (most 
notably for results of `autoheader').

 BTW, do we still want to carry local copies of severely obsolete libtool 
scripts?  I have had success with libtool 1.5.22 and GCC 4.1.1 after a 
moderate amount of work (mostly shuffling bits around; libjava/ was the 
most involving part) -- if there is interest in upgrading (which might 
help some people with less common configurations) I could port them to the 
trunk sooner rather than later.

 Indeed, though they are not fatal.  Perhaps Makefile.in files in the 
affected directories (Makefile.am are OK as sufficiently new automake will 
deal with that) could get updated beforehand?  It should not hurt at all.
