I can't think of any way that would be possible with a C preprocessor
since it doesn't support the notion of displaying "variable" data.  I
ended up writing a C program to dump out just the kind of "overview"
for a given Fosc that you're talking about:

$ baud 4000000

            Percent Error
  BPS    BRGH = 0   BRGH = 1
