mingw-w64 has had the _HEAPOK define since the initial commits in 2007; unclear when/where it was added for mingw.org headers, but it does seem to exist there as well (at least in versions from 2011).

This workaround stems from 53fbecce6e8b7d1f024e3dc6df4160fe9a577ff1 from 2004 - it is no longer relevant today.
