Jiri,
with pgcc/pgCC/pgf* version 13.8 you changed the output of 'pgcc -V' from
pgcc 13.4-0 64-bit target on Linux -tp penryn
Copyright 1989-2000, The Portland Group, Inc. All Rights Reserved.

to
pgcc 13.8-0 64-bit target on x86-64 Linux -tp penryn
Copyright (c) 2013, NVIDIA CORPORATION. All rights reserved.
Unfortunately, if pgcc/pgCC/pgf* is used via a wrapper, for example as a
MPI compiler wrapper, your change breaks autotools-based shared builds.
This is due to the following case statement in libtool's
'libltdl/m4/libtool.m4':
case `$CC -V 2>&1 | sed 5q` in
...
*Portland\ Group*)
lt_prog_compiler_wl='-Wl,'
lt_prog_compiler_pic='-fpic'
lt_prog_compiler_static='-Bstatic'
;;
...
Providing a libtool patch to handle 'NVIDIA CORPORATION' in this case
statement is easy (attached but untested). What isn't easy is to get a
patch into a libtool release and to get this release to the users. This
basically means that pgcc/pgCC/pgf* version >= 13.8 can not be used for
autotools-based shared MPI builds any longer. This affects e.g., Score-P
and Scalasca.
I don't know about your copyright notice policy at NVIDIA, but you would
help users if you would mention the previous copyright holders in 'pgcc
-V' as well, e.g.,
$ pgcc -V
pgcc 13.8-0 64-bit target on Linux -tp penryn
