Remove fluff, remove non-constrained limitation (wasn’t real anyway)
Which platforms return a non-null pointer on malloc(0)
Hi,I'm interested in the portability of `malloc(0);`.- - Which platforms return `NULL` without setting `errno`?
- - Which platforms return a non-null pointer?
- Do any platforms have a behavior that I didn't list?I'm especially interested in POSIX platforms, but I'd also appreciate information about non-POSIX ones.
