Great.

Well.  The story with -no-undefined is long and twisted, here's a
partial summary (from what I gathered):
http://article.gmane.org/gmane.comp.gnu.mingw.user/18727

Adding -no-undefined by the user at package build time is usually not
hard (by 'make LDFLAGS=-no-undefined' or similar), but removing it in
case issues arise is a bit more work.

But yes, if the package builds well with -no-undefined everywhere,
there's no reason not to add it.  (I should probably update my
recommendation in above article to have it added for $host_os matching
cygwin*, mingw*, and skyos*).

Cheers,
Ralf
