Well, if the structure is required for the compile that's OK; but note
that you still need to check for the proper features at run-time, just
because the structure was present at compile time doesn't mean the
kernel supports it, since you can build on 2.6 and then run on 2.4.
Also please use the existing macros for checking structure fields.
