GNU Fortran Command Options
***************************
The `g77' command supports all the options supported by the `gcc'
command. Note:GNU CC Command Options, for
information on the non-Fortran-specific aspects of the `gcc' command
(and, therefore, the `g77' command).
All `gcc' and `g77' options are accepted both by `g77' and by `gcc'
(as well as any other drivers built at the same time, such as `g++'),
since adding `g77' to the `gcc' distribution enables acceptance of
`g77'-specific options by all of the relevant drivers.
In some cases, options have positive and negative forms; the
negative form of `-ffoo' would be `-fno-foo'. This manual documents
only one of these two forms, whichever one is not the default.
