How about using a spx_int32_t filt_len temporary instead? That way you can avoid adding casts inside the loop and even delete one that's already there.

I'm wary about changing these index variables to unsigned as this has burned libspeex before: 1e2f99.
Less intrusive would be to promote the upper limit variable (e.g., len) to signed, or live with the warnings.

I can confirmed that with these changes, the resampling sounds the same (and I'd expect it to sound terrible if something wrapped that shouldn't). Tested with floating-point only, but the same branches are covered for fixed.
