Other Dialects
**************

   GNU Fortran supports a variety of features that are not considered
part of the GNU Fortran language itself, but are representative of
various dialects of Fortran that `g77' supports in whole or in part.

   Any of the features listed below might be disallowed by `g77' unless
some command-line option is specified.  Currently, some of the features
are accepted using the default invocation of `g77', but that might
change in the future.

   *Note: This portion of the documentation definitely needs a lot of
work!*
