Quite true. My changes were rather mechanical in the sense that I
simply searched for some constructs and fixed them in the passing,
using well-known other constructs from Autoconf.
The fact that these introduced a bug came surprising to me, but thanks
to your proofreading it now also helps to fix a bug in Autoconf itself.

Yep. Patches to Autoconf and Libtool coming up on their respective
lists. Patch for gnulib-tool below.

Apologies. Libtool uses slightly different indenting, which I have
gotten used to, and I forgot to readjust that here.
OK to apply this patch to fix these issues?
Cheers,
