Reproduce the opus-1.6.1 build with GCC 16 and inspect silk/float/pitch_analysis_core_FLP.c, especially lines 85, 157, and 168, alongside the silk_resampler_down2 declaration in silk/SigProc_FIX.h at line 78. Determine whether the warnings indicate a real issue, then validate that the build completes without them while preserving behavior.
