-# SYNOPSIS
-#
-# RW_PROG_CXX_WORKS
-#
-# DESCRIPTION
-#
-# RW_PROG_CXX_WORKS checks whether the C++ compiler works.
-#
-# There's a bit of oversight in autoconf that will set the C++ compiler to
-# g++ if no compiler is found, even if g++ is not present! So we need an
-# extra test to make sure that the compiler works.
