  # Helper function to deal with inclusion directory specs.
  # We're dealing with two issues:
  # 1. A lot of include directory specs take up a lot of command line real
  #    estate, and the DCL command line is very limited (2KiB).
  # 2. For optimal usage, include directory paths must be in Unix form,
  #    that's the only way the C compiler can merge multiple include paths
  #    in a sane way (we can stop worrying about 1.h including foo/2.h
  #    including ../3.h).
  #
  # To resolve 1, we need to create a file with include directory pragmas,
  # and let the compiler use it with /FIRST_INCLUDE=.
  # To resolve 2, we convert all include directory specs we get to Unix,
  # with available File::Spec functions.
  #
  # We use CRC-24 from https://tools.ietf.org/html/rfc4880#section-6,
  # reimplemented in Perl to get a workable and constant file name for each
  # combination of include directory specs.  It is assumed that the order of
  # these directories don't matter.
  #
  # This function takes as input a list of include directories
  # This function returns a list two things:
  # 1. The file name to use with /FIRST_INCLUDE=
  # 2. Text to insert into descrip.mms (may be the empty string)

      # The linking commands looks a bit complex, but it's for good reason.
      # When you link, say, foo.obj, bar.obj and libsomething.exe/share, and
      # bar.obj happens to have a symbol that also exists in libsomething.exe,
      # the linker will warn about it, loudly, and will then choose to pick
      # the first copy encountered (the one in bar.obj in this example).
      # On Unix and on Windows, the corresponding maneuver goes through
      # silently with the same effect.
      # With some test programs, made for checking the internals of OpenSSL,
      # we do this kind of linking deliberately, picking a few specific object
      # files from within [.crypto] or [.ssl] so we can reach symbols that are
      # otherwise unreachable (since the shareable images only exports the
      # symbols listed in [.util]*.num), and then with the shared libraries
      # themselves.  So we need to silence the warning about multiply defined
      # symbols, to mimic the way linking work on Unix and Windows, and so
      # the build isn't interrupted (MMS stops when warnings are signaled,
      # by default), and so someone building doesn't have to worry where it
      # isn't necessary.  If there are other warnings, however, we show them
      # and let it break the build.
