That's not a bad idea--a run-time check would be straightforward, although
a compile-time one would be nicer for the user. Another way would be
to do something like replace curl_easy_init (or curl_global_init or something
else) with a macro like this:

#define curl_easy_init() curl_easy_init_checksize(sizeof(off_t))

and let the library verify it. This means more overhead, though, so I'm
more in favour of the renamed config.h trick.
