Use libstdc++ in a linker.lf file with a scheme (IDFGH-6414)

[philippe44]

It's a funny problem: I want to move the .bss section of libstdc++ to extram. My linker.lf works with any other library, but it fails with libstdc++ saying there is "illegal nesting". I suspect that the "+" symbol is the culprit but I've tried different escape options and none worked...

It's here in fragments.py

class Fragment():
    __metaclass__ = abc.ABCMeta
    """
    Encapsulates a fragment as defined in the generator syntax. Sets values common to all fragment and performs processing
    such as checking the validity of the fragment name and getting the entry values.
    """

    IDENTIFIER = Word(alphas + '_', alphanums + '_')
    ENTITY = Word(alphanums + '.-_$')

    @abc.abstractmethod
    def set_key_value(self, key, parse_results):
        pass

    @abc.abstractmethod
    def get_key_grammars(self):
        pass

replace

    ENTITY = Word(alphanums + '.-_$')

by

    ENTITY = Word(alphanums + '.-_$+')
