          Issue ID: 23039
           Summary: importC: declaration with array length has itself in
                    scope
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: ImportC
          Severity: minor
          Priority: P1
         Component: dmd

const int x = 1;
void fn1() { char x[x]; }
struct S1 { char x[x]; };
//void fn2() { typeof(x) x; }
//struct S2 { typeof(x) x; };

these give circular reference errors in dmd but work in other compilers (except gcc doesn't like "struct S1" using the global)

found when testing the typeof PR, it is also affected
