   3 # This is an awk script which finds out what the possibilities for
   4 # the error names are, and dumps them out so that cpp can turn them
   5 # into numbers.  Since we don't need to decide here what the
   6 # real signals are, we can afford to be generous about definitions,
   7 # in case the definitions are in terms of other definitions.
   8 # However, we need to avoid definitions with parentheses, which will
   9 # mess up the syntax.
