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)

That would be fantastic.

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

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