#34 clang errors out libTFELSystem_la-ProcessManager-c when using inconsistent C++ flags.

[Pedro F. Giffuni]

This is new for 3.0.0 and doesn't happen in previous versions.
Setting the language standard inconsistently to '-std=c++11' when compiling C code is somethin clang doesn't like:
% cc --version

What is the output of make V=1 (only the first lines...)

This is much better !
I will commit the changes to the configure.ac and m4/gxx.m4 file in the rliv-3.0 and trunk branches tomorrow.
Thank you for your help.
I close the ticket, but do not hesitate if you have additonnal requests.
