branch: master
commit e5160fe0595d4b040864dec679ca22151d7b7357

    Revert "Add workaround for Boost.Regex compilation with clang 11"
    
    This reverts commit f62151ab4a23429fb05466f203fb937683907395 because it
    will be superseded by an alternative change in configure.ac in the next
    commit and is incompatible with it, as doing it both on the compiler
    command line and here would result in a -Wmacro-redefined.
