           Summary: clang rejects "__label__"
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Semantic Analyzer
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: kremenek at apple.com
                CC: llvmbugs at cs.uiuc.edu


gcc happily eats the following:

void foo(void) {
  __label__ bad;
  int x;
}

clang not so much:

$ clang t.c
t.c:6:3: error: expected expression
  __label__ bad;
  ^
1 diagnostic generated.

Not only does clang reject this, but the error message is suboptimal.
