[Dune] How to force -std=c++0x in a dune project?

[Arya Fallahi]

Dear Markus and Christoph,

Thank you very much for your hints. I followed your tips but there is still
problem. In fact, the return of "g++ --version" and "gcc --version" are
both the installed version 4.7.2, but in the config.log file I see the
following line:

configure:3337: checking for gcc
configure:3353: found /usr/bin/gcc
configure:3363: result: gcc
configure:3607: checking for C compiler version
configure:3610: gcc --version </dev/null >&5
gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-50)
Copyright (C) 2006 Free Software Foundation, Inc.

which is the default installation on Redhat. I agree that this is the sort
of the problem, but I could not remove it yet. I added CXX='g++' and
CC='gcc' to the optfile but it still had the same problem. The
recommendation from Markus also did not work. I am thinking of another
solution, but would be thankful to know about your ideas.

Thanks a lot,
Arya

P.S. @Christoph: I stop using the Dune Support team, but I still need a
name for the ones I write to. What about "Dune developers" ;-) ?
