Bug 22734 – importC: typedef anonymous enum members not available when used from D

With the following C file: // enu.c enum E_a { A, }; enum { B, }; typedef enum { C, } E_c; typedef enum E_d { D, } E_d; int a = A; int b = B; int c = C; int d = D; Which is then imported by the following D file: // use_enu.d import enu; auto d_a = A; auto d_b = B; auto d_c = C; auto d_d = D; You get the following errors: enu.c(19): Error: undefined identifier `C` use_enu.d(6): Error: undefined identifier `C` What is odd though is that if you compile enu.c directly: dmd enu.c -c You get no error, it is when you compile a D file dmd use_enu.d -c that you get the above errors.

In fact, you get the error in the C file even if you are not using the enum in your D file.
