Yes, it essentially changes the meaning of the AC_GNU_GETTEXT_VERSION
argument from == to >=.

Hmmm, hadn't thought about that, although I don't understand why an
actively developed package shouldn't be using gettext-0.17 already.

Exactly.

What about enabling the autopoint -V option (which is currently
commented out as "dangerous" on lines 164-166,212-222), and changing the
version mismatch error on line 276 into a message or warning?  Cygport
could then export AUTOPOINT="autopoint -V 0.17" when libtool usage is
detected.
