Comment (by sambthompson):

 Found this issue as well when rebuilding mkvtoolnix after the changes
 discussed in #xxxxx. Relates to a bug fix applied to clang-16 and later,
 discussed here: https://github.com/llvm/llvm-project/issues/50055

 Fixed it by cherry-picking this commit
 https://github.com/boostorg/numeric_conversion/commit/50a1eae942effb0a9b90724323ef8f2a67e7984a
 to the boost176 installation, found on Boost's version of this issue at
 https://github.com/boostorg/mpl/issues/69. This fix didn't land until
 Boost 1.81, so probably needs application to versions 1.77 thru 1.80 as
 well if clang16 support is wanted for these earlier versions.

 For mkvtoolnix, I also needed the fix for BOOST_NO_CXX98_FUNCTION_BASE
 found in https://github.com/boostorg/config/pull/440, which related to
 this issue: https://github.com/boostorg/container_hash/issues/24. This
 also didn't land until 1.81.
