>Description:
C enum with value 129 prints as -127.  Seems to be
sensitive to debug format because compiling with
stabs (gcc -gstabs a.c) prints the right value.
>How-To-Repeat:
[bughouse]$ cat a.c
enum {
        x = 129
};

main ()
{
        printf ("%d\n", x);
}
[bughouse]$ gcc -g a.c
[bughouse]$ gdb a.out
