Experimental support for building as C++

So far with the following caveats:
 - Triggers -Wc99-designator
 - Compound literals are non-standard.
 - The setjmp/longjmp in the configuration parser might be an issue.
 - Perhaps others.

It does not seem to be a good idea to use this library for C++ at all.
Much of what it does is directly replaced by the STL.
