For example, when a project is considering switching from C to C++, or 
even just evaluating the difficulty of it, it is a common first step to 
make it compilable by either compiler.  It is common enough that even 
GCC supports a -Wc++-compat warning to tell you if you've strayed from 
the common subset.

I'm very undecided, but I think I'm on Sam's side.  gt_NO_CXX is not 
even emitting a message to stdout, and even if it was saying

  checking if ${CC} is a C++ compiler... yes/no

it wouldn't look out-of-place in a configure script's output.
