        Thank you for your response.

        The problem is I WANT all those little annoying warnings for MY
code just not for the COMPILER'S code.  I have found that code that
produces no warnings when the '-Wall -pedantic' flags are used is VERY
portable between different compilers and between different machine
architectures.  
        A compiler that complains about its own code seems weird.  In
B20.1 this this problem did not occur, perhaps the compiler should be
re-looked at in the net release.
