    libtool: avoid non-underscore symbols in the "dumpbin -symbols" wrapper
    
    If an object has a symbol lacking an expected leading underscore,
    the symbol name is not printed, but the symbol type is, leading
    to output such as:
        T _normal _normal
        T T _another _another
    when the expected output would have been something like:
        T _normal _normal
        T no_underscore no_underscore
        T _another _another
    However, symbols lacking an expected leading underscore are
    not "real" symbols, they are internal symbols which we don't
    care about, therefore drop them instead.
    * m4/libtool.m4 (_LT_CMD_GLOBAL_SYMBOLS) [MSVC]: Output the whole
    symbol line in one go.
    * NEWS: Update.
