+dnl intrinsic and run-time libraries that are required to successfully

+dnl
+dnl This macro is intended to be used in those situations when it is
+dnl necessary to mix, e.g. C++ and Fortran 77, source code into a single
+dnl program or shared library.
+dnl
+dnl For example, if object files from a C++ and Fortran 77 compiler must
+dnl be linked together, then the C++ compiler/linker must be used for
+dnl linking (since special C++-ish things need to happen at link time
+dnl like calling global constructors, instantiating templates, enabling
+dnl exception support, etc.).
+dnl
+dnl However, the Fortran 77 intrinsic and run-time libraries must be
+dnl linked in as well, but the C++ compiler/linker doesn't know how to
+dnl add these Fortran 77 libraries. Hence, the macro
+dnl `AC_F77_LIBRARY_LDFLAGS' was created to determine these Fortran 77
+dnl libraries.
+dnl
+dnl This macro was packaged in its current form by Matthew D. Langston
+dnl <langston@SLAC.Stanford.EDU>. However, nearly all of this macro
+dnl came from the `OCTAVE_FLIBS' macro in `octave-2.0.13/aclocal.m4',
+dnl and full credit should go to John W. Eaton for writing this
