           Summary: clang: nested functions not supported?
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

Testcase:
void foo()
{
    void bar() {
    }
}

Results in:
p2.c:3:15: error: expected ';' at end of declaration
    void bar() {
              ^
              ;                                                                 
1 error generated. 

This blocks compilation of thinkpad_acpi.c from the Linux kernel:

declaration                                                            
                             const unsigned int newvol)
                                                       ^
                                                       ;
