daan	2affdbbd2e	stronger secure mode when defining MI_SECURE=4: checks for double free, corrupted free list, and invalid pointer frees. Performance is impacted but not too much -- more perf testing is needed	2019-10-18 18:11:04 -07:00

Johannes Schindelin	0fd0122c0a	Avoid compiler warning when casting the result of GetProcAddress() ... It is most unfortunate that the return type of `GetProcAddress()` is `FARPROC` (which is essentially `intptr_t(*)(void)): this type cannot be cast by GCC without warnings to anything but the generic function pointer type `void(*)(void)`. Let's work around that. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>	2019-10-17 20:43:18 +02:00
Johannes Schindelin	5bd8ea2e4f	Repeat mi_decl_allocator in functions' definitions ... Quite a few functions are declared with that attribute, and VS 2019 complains if the definition does not repeat it. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>	2019-10-17 20:43:18 +02:00
