I quote Todo:

        generalise Errno way of extracting cpp symbols and use that in
            Errno and Fcntl (ExtUtils::CppSymbol?)

Without an _automated_ *.h->(PL)->.{xs,pm,ph} transformation there is
no way we can get all the particular defines of a particular platform.
I have started many times doing the above generalisation step.  If
somebody feels like it, they can have my latest attempt.  h2xs and
h2ph have a lot of the required logic already.
