off_t weirdness

Try this on a Linux+glibc+GCC system:

#include <assert.h>
#include <ruby.h>
#include <sys/types.h>

int
main(void)
{
	return sizeof(off_t);
}

on my system the result is 4.  Now, if I write this as

#include <ruby.h>
#include <assert.h>
#include <sys/types.h>

int
main(void)
{
	return sizeof(off_t);
}

instead, the result is 8.  This "bug" set me back about an hour of
work, which kind of sucked.  This behavior worries me a bit, as there
may be places where ruby.h isn't included and the sizeof(off_t) will be
4 and others where it is included and the sizeof(off_t) will be 8,
causing all weird kinds of behavior.  Is there a reason for why this is
so, or is it simply a problem in how my system has set up its headers?,
