(g77.info) G77 and GCC

 
 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.
 
     Compile C; C++; or Objective-C (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.
