The allocator interface is defined via these names. Just supply your own realloc. Of course you need to satisfy the constraints of realloc guaranteed to the compiler, or you need to invoke it in freestanding mode.

That doesn't work for pool allocators like https://apr.apache.org/docs/apr/1.5/group__apr__pools.html and neither does it work for our allocator https://docs.frrouting.org/projects/dev-guide/en/latest/memt... that takes an allocation group argument.
