Absoultely an absurdity. Of course mingw-w64 provides an errno.h
header. Not sure where you expect headers are and what content by
your expectations they shall have, but I would recomment that you
might try before starting to do fural guessings.
PS: The native toolchain and cygwin don't share most of the
C-runtime-headers by good reasons.
