    libstdc++: Remove noexcept-specifier from MCF __cxa_guard_acquire [PR116857]
    
    This function definition should not be marked as non-throwing, because
    the declaration in <cxxabi.h> is potentially throwing.
    
    Also fix whitespace.

            PR libstdc++/116857
            * libsupc++/guard.cc (__cxa_guard_acquire): Remove
            _GLIBCXX_NOTHROW to match declaration in <cxxabi.h>.
    
    (cherry picked from commit efdda203f52b9b55ef9acc8ad668bbd0570a8de6)
