            Bug ID: 31936
           Summary: Low-quality error message using __declspec without
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs
          Assignee: unassignedclangbugs at nondot.org
          Reporter: efriedma at codeaurora.org
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

C Testcase:
__declspec(noreturn) int f();

Error message:
<stdin>:1:26: error: parameter named 'f' is missing
__declspec(noreturn) int f();
<stdin>:1:30: error: expected function body after function declarator
__declspec(noreturn) int f();
2 errors generated.

clang is trying to parse this as a old-style C function definition, which leads
to an error message which is difficult to understand.
