I agree 100% with Roland on this one. There's a reason that compilers
don't complain about this particular cast. Casting from integer type to
integer type just isn't a big deal in my book.
Of course,I generally try to avoid casts at all costs, since they tend to
cover real issues (see all the evil casts of long* to int* that have
screwed us continually with 64 bit big endian machines.
But I don't care enough to argue the point :).
