+ *      -DNPRINT
+ *
+ *          Disable all printing.  stdio.h will not be included.  Printing can
+ *          be re-enabled at run-time by setting the global pointer amd_printf
+ *          to printf (or mexPrintf for a MATLAB mexFunction).
+ *
+ *      -DNMALLOC
+ *
+ *          No memory manager is defined at compile-time.  You MUST define the
+ *          function pointers amd_malloc, amd_free, amd_realloc, and
+ *          amd_calloc at run-time for AMD to work properly.

+ * and mxAssert is used instead of assert.  If debugging is not enabled, no
+ * MATLAB include files or functions are used.  Thus, the AMD library libamd.a
