            Bug ID: 61006
           Summary: libcpp/lex.c: must use 'enum' tag to refer to type
                    "raw_str_phase"
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: spamcop at tgos dot net

gcc-4.9.0/libcpp/lex.c:1394

The original line is:

    raw_str_phase phase = RAW_STR_PREFIX;

This is incorrect. It must be:

    enum raw_str_phase phase = RAW_STR_PREFIX;

Because raw_str_phase is an enum type, it isn't typedef'ed and lex.c is a C
file (not a C++ file). As a result, when building with clang, it correctly
complains:

"must use 'enum' tag to refer to type 'raw_str_phase'"
