           Summary: importC: Error: cannot modify 'const' expression
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW

It looks like 'const char*' is being translated to 'const(char*)' instead of
'const(char)*'.

Reduced test:
---
void test(const char *buf)
{
  int a = *buf++;
}
