    Disable clang enum-related warnings in C++20 mode
    
    Using -std=c++20 implicitly enables a few warnings that occur in lmi
    code and can't be easily fixed, so disable them for now.

     dnl Many instances of these warnings are given in Boost 1.33.1 headers, so
     dnl we unfortunately have to disable them even if they're potentially
     dnl useful, especially the latter one.
