fshort-enums broken in egcs-1.1.1

Please send me a copy of any responses to this posting as I am not

I just discovered the following bug in trying to compile KnightCap
(a chess program) on Linux/x86 using egcs-1.1.1.  I verified that
this bug does not exist when I use the gcc-2.7.2.3 compiler so I think
it's egcs-specific.

If I compile the following code with no compiler flags, it prints 
a list of numbers from 0 to 63.  But if I compile with the -fshort-enums
flag (as the KnightCap Makefile is set to do by default)  the loop 
fails to terminate.

-----------sample code follows-------------------    

typedef enum {A1=0, A2, A3, A4, A5, A6, A7, A8,
              B1, B2, B3, B4, B5, B6, B7, B8,
              C1, C2, C3, C4, C5, C6, C7, C8,
              D1, D2, D3, D4, D5, D6, D7, D8,
              E1, E2, E3, E4, E5, E6, E7, E8,
              F1, F2, F3, F4, F5, F6, F7, F8,
              G1, G2, G3, G4, G5, G6, G7, G8,
              H1, H2, H3, H4, H5, H6, H7, H8} SquareT;

typedef SquareT Square;

bug(){
        Square p;
        for (p=A1;p<=H8;p++){
                printf("%d\n", (int)p);
        }
}

main(int argc, char **argv){
        bug();
}
