CYGWIN: warning on missing safe memzero() is printed #148200
Description
Bug report
Bug description:
Compiling on CYGWIN gives this message on the console:
warning: Your platform does not support any safe implementation of memzero -- consider a pull request!
However, CYGWIN provides explicit_bzero(), actually.
The Modules/_hacl/Lib_Memzero0.c already supports it, so, a tiny fix is required for just adding __CYGWIN__ to the list of supported platforms.

Hello, with the release of the new beta version 3.15.0b1, I'm wondering if it would be possible to sync the sources of hacl from upstream or by applying the linked PR, which does the same thing. Thank you very much.
