Bug description:
Compiling under CYGWIN prints these warning messages:

Looking into the code of Objects/mimalloc/prim/unix/prim.c, there is already a conditional block to avoid the generation of such warnings.
The solution for this issue is to simply add CYGWIN to that list of platforms.
So, I'm posting this issue according to the suggestion received into #146572 for tracking this change.
