Won't help.  Installation instructions often say that at least version
xyz of library foo is required; it is the usual practice to detect
violations of this in ./configure where this is feasible.

The issue is that an incorrect diagnostic is emitted.  The configure
script tests for prerequisite X, and if it is not found, it should say
so.  It should not issue a message indicating that the language is
missing, because it is not.

Those complaints will cease one configure detects the situation and
issues a proper diagnostic.
