/* 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.
