FWIW, this mention does not need to be a copyright notice; it simply needs 
to be some text in the first 5 lines of the "pgcc -V" output that matches 
the "*Portland\ Group*" pattern.

In any case, Christian, if you can provide a reasonably obvious libtool 
patch to handle "NVIDIA CORPORATION", I can at least review it and get it 
committed to trunk ... though, given the sample output you list, I wonder if 
it would be better to just match 'pgcc\ [0-9].*' or something like that.  If 
we match "NVIDIA CORPORATION", it is likely to match other NVIDIA compilers 
(e.g., CUDA?) as well as having this issue again if they decide to change 
their capitalization or sell the compiler to another party.
