110 Currently, we only guarantee that I32 is *at least* 32 bits.
111 Specifically, if int is 64 bits, then so is I32. (This is the case
112 for the Cray.) This has the advantage of meshing nicely with
113 standard library calls (where we pass an I32 and the library is
114 expecting an int), but the disadvantage that an I32 is not 32 bits.

JH		 729 * Known problems:
730 * - all memory allocs do not get logged, only those
731 * that go through Newx() and derivatives (while all
732 * Safefrees do get logged)
733 * - __FILE__ and __LINE__ do not work everywhere
734 * - __func__ or __FUNCTION__ even less so
735 * - I think more goes on after the perlio frees but
736 * the thing is that STDERR gets closed (as do all
737 * the file descriptors)
738 * - no deeper calling stack than the caller of the Newx()
739 * or the kind, but do I look like a C reflection/introspection
740 * utility to you?
741 * - the function prototypes for the logging functions
742 * probably should maybe be somewhere else than handy.h
743 * - one could consider inlining (macrofying) the logging
744 * for speed, but I am too lazy
745 * - one could imagine recording the allocations in a hash,
746 * (keyed by the allocation address?), and maintain that
747 * through reallocs and frees, but how to do that without
748 * any News() happening...?
