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