+/* Fortran interface for the C-callable AMD library (int version only).  This
+ * is HIGHLY non-portable.  You will need to modify this depending on how your
+ * Fortran and C compilers behave.  Two examples are provided.
+ *
+ * To avoid using I/O, and to avoid the extra porting step of a Fortran
+ * function, the status code is returned as the first entry in P (P [0] in C
+ * and P (1) in Fortran) if an error occurs.  The error codes are negative
+ * (-1: out of memory, -2: invalid matrix).
+ *
+ * For some C and Fortran compilers, the Fortran compiler appends a single "_"
+ * after each routine name.  C doesn't do this, so the translation is made
+ * here.  Some Fortran compilers don't append an underscore (xlf on IBM AIX,
+ * for * example).
+ *
+ * Tested with the following compilers:
+ * Solaris with cc and f77 from Sun WorkShop 6 update 1.
+ * SGI Irix with MIPSpro cc and f77 compilers version 7.4
+ * Linux with GNU gcc or Intel's icc, and GNU g77 Intel's ifc Fortran compiler.
+ *	(any combination).  Note that with g77, a call to amd_order in Fortran
+ *	gets translated to a call to amd_order__, with two underscores ("_").
+ *	Thus, the Fortran names do not include an underscore.
