 810   # 2. For optimal usage, include directory paths must be in Unix form,
 811   #    that's the only way the C compiler can merge multiple include paths
 812   #    in a sane way (we can stop worrying about 1.h including foo/2.h
 813   #    including ../3.h).
 814   #
 815   # To resolve 1, we need to create a file with include directory pragmas,
 816   # and let the compiler use it with /FIRST_INCLUDE=.
 817   # To resolve 2, we convert all include directory specs we get to Unix,
 818   # with available File::Spec functions.

 821   # reimplemented in Perl to get a workable and constant file name for each
 822   # combination of include directory specs.  It is assumed that the order of
