Following up to my own post with a little more data.  The CUDA compiler 
driver has this version info:

$ nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2013 NVIDIA Corporation
Built on Wed_Jul_17_18:36:13_PDT_2013
Cuda compilation tools, release 5.5, V5.5.0

I'm not very comfortable with the idea of relying on case to distinguish 
"NVIDIA CORPORATION" meaning pgcc from "NVIDIA Corporation" meaning nvcc -- 
or, given the inconsistency, with assuming that NVIDIA won't make those 
consistent in a release or two.  Matching "pgcc\ [0-9].*" or the equivalent 
seems like the right thing to do.
