Created attachment 460346 [details, diff] for Cygwin, pull in sys-libs/cygwin-crypt Cygwin uses newlib, which does not include the ancient libcrypt. Even installing their 'cygwin-devel' package does not pull their 'crypt-devel'. For Prefix (guest) I prefer to not depend on anything else than the host's "libc" headers and libs. Ok?
you don't need our stamp to add prefix targets like this to virtual/libc
pushed, thanks
