Subject: A(nother?) Turbo C bug: #if / enum

The following abstracted code fragment erroneously produces a
"Duplicate case" compile error in my copy of Turbo C (purchased
locally within the last week):

typedef enum {
                beef,
#if 0
                mystery,
#endif
                lamb
             } MeatType;

frob(specimen)
  MeatType specimen;
{
  switch(specimen) {
    case beef:
      return(1);
    case lamb:
      return(2);
    default:
      return(0);
  };
}


If the #if / #endif are replaced by /* ... */, the problem disappears.

Does anybody recognize this as an old bug with an available fix?

On the positive side, Turbo C has successfully compiled a medium-sized
(110KB) application program, with surprisingly good object code
size and execution speeds.  The above bug stands in the way of seeing
how it does with a monster (420K + overlays) application.
