dnl Definitions of error numbers have become more and more general, so
dnl pick the file with the most matches, which must be at least 7.
dnl make a list of files containing any definitions in and keep them all.
dnl Careful with cut and paste in the pattern: the square brackets
dnl must contain a space and a tab.
