Yes it is the macro define-prim-vector-procedures, which defines
[string|vector|u8vector|s8vector|...]-[ref|set!|copy|append|...].

The compiler would have to keep a database of all the Gambit-specific
functions in the runtime. But this would tie the compiler to a
specific runtime **implementation** which is not desirable. Gambit
is designed to support multiple runtime systems.
There is a simple rule you can follow to avoid this kind of problem.
Never redefine or mutate a variable whose name starts with "##"
because this is the Gambit internals namespace. I guess the compiler
could give a warning for this case.
