This is not the right kind of test. You want to test whether time_t and int are 
the same types, not whether they're the same size. To do that, you should use 
code like this:

extern time_t foo;
extern long int foo;

Of course this means you'll need to compile N programs rather than one, but 
that's life in the big Autoconf city.
