I tried building with MONITOR_HEAP defined for the first time in a
while. It wasn't pretty.
date.c was calling libc's strdup() instead of our dupstr() so alloc.c
wasn't tracking those allocations when/if MONITOR_HEAP is enabled.
Then it called free() which is actually a call to nhfree() in that
situation. If the file of allocations and releases was subsequently
fed to heaputil, it would complain about freeing pointers that hadn't
been allocated.
Worse, makedefs and tilemap wouldn't link. For MONITOR_HEAP,
makedefs was undefining free() in order to avoid nhfree() but it now
links with date.o so got nhfree() calls anyway. And it wouldn't link
because that routine isn't available without alloc.o. tilemap
doesn't link with date.o but it does call malloc() and free() and it
wasn't undefining free(), so looked for nhfree() when linking and got
the same no-such-routine failure.
