 834   # 2. For optimal usage, include directory paths must be in Unix form,
 835   #    that's the only way the C compiler can merge multiple include paths
 836   #    in a sane way (we can stop worrying about 1.h including foo/2.h
 837   #    including ../3.h).
 838   #
 839   # To resolve 1, we need to create a file with include directory pragmas,
 840   # and let the compiler use it with /FIRST_INCLUDE=.
 841   # To resolve 2, we convert all include directory specs we get to Unix,
 842   # with available File::Spec functions.
 843   #
 844   # We use CRC-24 from https://tools.ietf.org/html/rfc4880#section-6,
 845   # reimplemented in Perl to get a workable and constant file name for each
 846   # combination of include directory specs.  It is assumed that the order of
