I do.  People can rightly expect linking C++ code to work under both
BSD-like systems as well as GNUish systems as well as, for example,
Solaris/CC where -lstdc++ is spelled "-lCstd -lCrun".  Libtool promises
to keep the normal user from being exposed to these differences.

Ahh, very good question.  Here we have an issue: it should be possible
to _override_ the decision of libtool to add -lstdc++ on OpenBSD in all
cases.  But those cases, in my opinion, would be the exception rather
than the rule: they are usually the cause when your package makes use of
some system-specifics anyway.  (Maybe there is even a way to detect
whether supc++ is preferable over stdc++; I don't know of one, though,
and in this case guessing is probably worse than allowing an override.)

Can we agree on this somehow?  What other issues, if any, are you
experiencing?
