This defines a family of functions and not all pools use them all.
One workaround is to annotate them, like this:

 #ifdef __GNUC__
 #define MAYBE_UNUSED __attribute__((__unused__))
 #else
 #define MAYBE_UNUSED
 #endif

 #define obj_pool_gen(pre, obj_t, initial_capacity) \
 ... \
 static MAYBE_UNUSED void pre##_init(void) \
 { \
 ...

Could that work here?

The “unused” attribute was added in gcc 2.7.
