+This is a "problem" test in Ada versus the C equivalent.  In C,
+we used macros to :
+
+  + declare a LOT of local integer and floating point variables
+  + load them with values
+  + check them at certain times
+  + to avoid floating point operations on CPUs w/o hardware support
+
+The macros are not equivalent to subprograms doing the same thing.
+We are trying to insure that the register set is fully utilized and
+checking that it survives context switches.  If the routines are
+subprograms, then calling conventions and scoping rules apply.  Thus
+the variables do not exist throughout the entire life of the task
+as in the C test.
+
+It seems to point out that although the conditional compilation
+and macro capabilities of C are often abused, they do provide
+capabilities which are difficult if not impossible to mimic entirely
+with subprograms.
