Subject Re: Building proton-c: cc1: error: unrecognized command line option "-Wvla" (RHEL 5.3)

Hmmm.  You raise a good point.

On the one hand, we want people to be policed by these flags if they
are contributing to the proton-c work.  However, we don't want proton
to be difficult to build for anybody else.

I will raise a JIRA to have the CMakeLists.txt only set the flags if
the gcc version can handle it, and print some inspirational message
otherwise.
