    libstdc++: Fix -Wmaybe-uninitialized false positive [PR103984]

    This fixes a false positive warning seen with LTO:

    12/bits/regex_compiler.tcc:443:32: error: '__last_char._M_char' may be used
uninitialized [-Werror=maybe-uninitialized]

    Given that the std::regex code is not very efficient anyway, the
    overhead of initializing this byte should be minimal.

    libstdc++-v3/ChangeLog:

            PR middle-end/103984
            * include/bits/regex_compiler.h (_BracketMatcher::_M_char): Use
            default member initializer.
