Neil --
Understood. Sorry, I think I left some context out here...
I am actually the one responsible for the Libtool support for pgcc
(because people on this list have been asking for LAM support for PGI).
I have been unsuccessfully trying to contact PGI for quite some time
to verify that the Libtool PGI support is correct (clearly, it isn't)
and/or to get their assistance to make it correct. Just to clarify --
I am *not* a Libtool expert -- hacking around in their code base is
quite confusing, and clearly I haven't gotten it right yet. :-\
I have received one vague e-mail back from PGI support that did not
include any technical information (they've been CC'ed on all my posts
to libtool-users_at_[hidden]).
The latest beta (b14) reflects Libtool 1.5.14 with a patch that is
currently slated to be included in LT 1.5.16 for "better" (but
apparently still not correct) PGI support. The current patch passes
the entire Libtool test suite (which is why it's slated for LT 1.5.16),
but apparently there's some corner cases with the PGI compiler suite
that it misses.
