Compiler Intrinsics
===================

   `g77' offers an ever-widening set of intrinsics.  Currently these
all are procedures (functions and subroutines).

   Some of these intrinsics are unimplemented, but their names reserved
to reduce future problems with existing code as they are implemented.
Others are implemented as part of the GNU Fortran language, while yet
others are provided for compatibility with other dialects of Fortran
but are not part of the GNU Fortran language.

   To manage these distinctions, `g77' provides intrinsic _groups_, a
facility that is simply an extension of the intrinsic groups provided
by the GNU Fortran language.

Fortran language.
