Can you be bothered to share it with us?  Has it hung enough to be
considered for Automake?

Sure -- it's attached.

I don't know if it's "good enough" to be considered for AM; it's really a shotgun approach (I don't know anything about their coding standards):

- make a temp dir, cd into it
- compile some C++ stuff that contains templates
- remove all known files
- see what files/dirs are left

There's probably other ways to do it; I have dim recollections of this macro coming into existence around 3am one night... :-)

(looking at this code again -- it's been years since I've examined it -- there's a *lot* that would need to be cleaned up and generalized; I am realizing how much I didn't know about AC when I wrote that macro -- it's embarrassing! ;-) The shotgun approach idea can be extracted from this code, if it's useful -- that's probably about it)

Has something changed that I no longer need to do this?

We might want to have something like it.

That would be fantastic.

[Template.dir stuff snipped]

I'll let the PGI people reply to this stuff...

Does anybody have some real-world code using C++/templates/libraries
that I (or, even better, you) can test with (and that is not too
complicated to set up)?

'fraid not. We only needed C libraries to build with LAM/MPI -- the C++ templating issue came up after that was solved. Sorry! :-(
