+ * When using the debug MS CRT allocator, each allocation stores the
+ * callsite __FILE__ and __LINE__, which is then displayed at process
+ * termination, to track down leaks.  We don't want all of our
+ * allocations to show up as coming from emalloc.c, so we preserve the
+ * original callsite's source file and line using macros which pass
+ * __FILE__ and __LINE__ as parameters to these routines.
+ * Other debug malloc implementations can be used by defining
+ * EREALLOC_IMPL() as ports/winnt/include/config.h does.
