          Issue ID: 22611
           Summary: ImportC: Need better error messages involving structs
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: lance at lancebachmeier.com

C code:

typedef struct
{
   unsigned char c[4];
} stb_easy_font_color;
stb_easy_font_color c = { 255,255,255,255 }; // use structure copying to avoid
needing depending on memcpy()

DMD output:

Error: 3 extra initializer(s) for `struct __tag21`

__tag21 is generated by the compiler, so the alias stb_easy_font_color should
be reported instead.
