          Issue ID: 24373
           Summary: ImportC: .di generator can output invalid aliases
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: ImportC
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: dave287091@gmail.com

Example c file:

typedef unsigned int uint;
typedef unsigned short ushort;

If you then convert to a .di file, you get something like:

extern(C)
{
 // ... bunch of junk
        alias uint = uint;
        alias ushort = ushort;
 // ...
}

Which are not valid alias declarations.
