  # These are horrible hacks, but are needed because recursive inclusion of
  # files in different directories does not work well with VMS C.  We try to

  # format, relative to the directory where the .c file is located.  The logic
  # is that any inclusion, merged with one of these relative directories, will
  # find the requested inclusion file.
  # In the regexps, it's advisable to always start the file name with .*?, as
  # the C source to OBJ file translation adds stuff at the beginning of the,
  # name, such as [.ssl]bio_ssl.c -> [.ssl]libssl-shlib-bio_ssl.OBJ

  # 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 linker will warn about it, loudly, and will then choose to pick

      # With some test programs, made for checking the internals of OpenSSL,

      # 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.
