Options 

A user reported a bug that configure should die when g++ isn't
installed, but wasn't:
http://code.google.com/p/google-perftools/issues/detail?id=217

This turned out to be a bug in autoconf:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=357378

The workaround is simple: check for CXX before checking for
CC.  This means that if g++ is installed but gcc isn't, we
won't die (at cc-checking time), but I tested, and the
configure script dies later.  In any case, it seems unlikely
someone would have a c++ compiler installed but not a c
compiler.

This fixes the 4 opensource projects I work on that are
susceptible to this.
