Compiler warning in Opus 1.5.2 (1/3)

When compiling Opus 1.5.2 within the Jamulus project on either X86_64 (Debian 12) or ARM (Raspbian 12), the following compiler warning is emitted:

gcc -c -pipe -O2 -D_REENTRANT -Wall -Wextra -fPIC -DAPP_VERSION=\"3.11.0dev-0cc2cbf2\" -DCUSTOM_MODES -D_REENTRANT -DQT_NO_DEPRECATED_WARNINGS -DHAVE_LRINTF -DHAVE_STDINT_H -DWITH_JACK -DOPUS_BUILD=1 -DUSE_ALLOCA=1 -DOPUS_HAVE_RTCD=1 -DHAVE_LRINTF=1 -DHAVE_LRINT=1 -DQT_NO_DEB

libs/opus/src/repacketizer.c: In function ‘opus_repacketizer_out_range_impl’:
libs/opus/src/repacketizer.c:305:11: warning: unused variable ‘ret’ [-Wunused-variable]
  305 |       int ret = opus_packet_extensions_generate(&data[ext_begin], ext_len, all_extensions, ext_count, 0);
      |           ^~~

The offending code in src/repacketizer.c is this:

   if (ext_len > 0) {
      int ret = opus_packet_extensions_generate(&data[ext_begin], ext_len, all_extensions, ext_count, 0);
      celt_assert(ret == ext_len);
   }

For a production build, where celt_assert() expands to nothing, the variable ret is unused.

The warning can be suppressed by adding a void reference to the variable:

   if (ext_len > 0) {
      int ret = opus_packet_extensions_generate(&data[ext_begin], ext_len, all_extensions, ext_count, 0);
      (void)ret;    /* suppress unused warning when celt_assert() is not enabled */
      celt_assert(ret == ext_len);
   }

I have checked this hasn't already been addressed in the most recent commits.
