Compile Fortran, C, or Other Programs

   A GNU Fortran installation includes a modified version of the `gcc'
command.
   In a non-Fortran installation, `gcc' recognizes C, C++, and
Objective-C source files.
   In a GNU Fortran installation, `gcc' also recognizes Fortran source
files and accepts Fortran-specific command-line options, plus some
command-line options that are designed to cater to Fortran users but
apply to other languages as well.
   *Note Compile C; C++; Objective-C; Ada; Fortran; or Java: (gcc)G++
and GCC, for information on the way different languages are handled by
the GNU CC compiler (`gcc').
   Also provided as part of GNU Fortran is the `g77' command.  The
`g77' command is designed to make compiling and linking Fortran
programs somewhat easier than when using the `gcc' command for these
tasks.  It does this by analyzing the command line somewhat and
changing it appropriately before submitting it to the `gcc' command.
   Use the `-v' option with `g77' to see what is going on--the first
line of output is the invocation of the `gcc' command.
