In case of errors please change into the directory with error and run 'make'.
If you get multiple errors, you need to deal with them in the order they
appear in the error log. If you get an error building a library, you will
also get errors from anything which uses the library.

i tried to change in grass_trunk/lib/python/ctypes/ctypesgencore/parser/pplexer.py  to :

class StringLiteral(str):
    def __new__(cls, value):
        assert value[0] == '"' and value[-1] == '"'
        # Unescaping probably not perfect but close enough.
        try:
            value = value[1:-1].decode('string_escape')
        except ValueError, e:
            value = re.sub(r'\\x([0-9a-fA-F])(?![0-9a-fA-F])', r'\x0\1', value[1:-1]).decode('string_escape')
        return str.__new__(cls, value)


but print out a lot of syntax errors, 
maybe i changed it wrong,
if usefull i can try to rebuild and attach the log.
