    c++: Fox template-introduction tentative parsing in class bodies clear
colon_corrects_to_scope_p [PR105061]

    The concepts support (in particular template introductions from concepts
TS)
    broke the following testcase, valid unnamed bitfields with dependent
    types (or even just typedefs) were diagnosed as typos (: instead of correct
    ::) in template introduction during their tentative parsing.
    The following patch fixes that by not doing this : to :: correction when
    member_p is true.

            * parser.c (cp_parser_template_introduction): If member_p,
temporarily
            clear parser->colon_corrects_to_scope_p around tentative parsing of
            nested name specifier.
