  Instead of writing 
    #ifdef DOS
    do dos-like stuff
    #endif

  You write
    #ifdef HAVE_SOME_FEATURE
    do code to handle that feature
    #endif

What would be most helpful for those of us using non-Unix systems 
(whether Win32, OS/2, DOS, VMS or other) is not to embed knowledge
about things like filenames all over the place, but instead use functions
or macros like IS_DIR_SEP(X), IS_ROOTED_PATH(X) to test for directory 
separators or rooted paths.

Such definitions can be set in the appropriate configuration files
and then there is no need for #ifdef's in the actual code.
