Other macros should rarely need to run @code{echo} directly to print

easy to change how and when each kind of message is printed; such
changes need only be made to the macro definitions, and all the callers
change automatically.

The @var{feature-description} should be something like @samp{whether the
Fortran compiler accepts C++ comments} or @samp{for c89}.
