Ugg - sounds like the gnulib warnings-detection module that m4 uses
needs to be taught how to recognize Sun Studio's behavior when a
particular compiler flag is unsupported.  This is a gnulib issue, and
will affect more than just m4, so fixing it upstream will also solve the
problem for multiple packages.
