we're talking about malloc.h here.  this is already a non-standard header.
the standard malloc APIs are defined in stdlib.h:
https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/stdlib.h.html

so i'm not sure how much value there is annotating standards in a header
that is not in any standard, and whose inclusion clearly declares "i am
not conforming to any standards".

we could put a disclaimer/explanation at the top of the header file to
make this a bit more clear.
