Hmph, it seems like fseeko() may be prototyped differently in different
versions of the same OS: OSX SDK <= 10.4 has the offset as fpos_t which
is defined either as __int64_t or __darwin_off_t, but as off_t in 10.5.
So what I said previously seems wrong.

OTOH, the need for sys/types.h is there unless the cast is removed..
