You seem not to have read my response to your earlier mail proprosing
such a thing (for tags only, not cscope):

    http://boudicca.tux.org/hypermail/linux-kernel/2001week21/1869.html

How does the patch above fix anything?  You're sorting so that
include/linux/*.h comes before include/linux/{mtd,lockd,raid,...}/*.h,
but I don't see how that can be an improvement, or how it addresses
your original complaint "ctags doesn't honour any CPP #if'ing".
