Distensions

   The `-fugly-*' command-line options determine whether certain
features supported by VAX FORTRAN and other such compilers, but
considered too ugly to be in code that can be changed to use safer
and/or more portable constructs, are accepted.  These are humorously
referred to as "distensions", extensions that just plain look ugly in
the harsh light of day.
