re: lib/34516: size_t should be equivalent to unsigned long

[matthew green <mrg%eterna.com.au@localhost>]

    Furthermore, the precise expansion of size_t is gcc's choice, because
    gcc "knows" the type signatures of various standard functions, so we
    can't or shouldn't change it in NetBSD even if there were a good
    argument in favor.


we infact have changed the definition of size_t on at least 1
platform, and i think a couple more as well.

it means that your build has warnings next time, but it's not
very much of a big deal to do.

(we did this on sparc, so that the type was consistent between
32 and 64 bit.)
