new offset outside bounds of constant string warning

[Ben Elliston]

Hi HJ

According to svn annotate, it was you who authored the new 'offset
outside bounds of constant string warning' warning in GCC (well, I think
so, anyway).  The compiler now complains about some code in the C++
demangler:

/home/bje/source/gcc-trunk/libiberty/cplus-dem.c:2651: warning: offset ‘3’ 
outside bounds of constant string

I tracked this down to the definition of strspn used on my Linux system:

#   define strspn(s, accept) \
  __extension__                                                               \
  ({ char __a0, __a1, __a2;                                                   \
     (__builtin_constant_p (accept) && __string2_1bptr_p (accept)             \
      ? ((__builtin_constant_p (s) && __string2_1bptr_p (s))                  \
         ? __builtin_strspn (s, accept)                                       \
         : ((__a0 = ((__const char *) (accept))[0], __a0 == '\0')             \
            ? ((void) (s), 0)                                                 \
            : ((__a1 = ((__const char *) (accept))[1], __a1 == '\0')          \
               ? __strspn_c1 (s, __a0)                                        \
               : ((__a2 = ((__const char *) (accept))[2], __a2 == '\0')       \
                  ? __strspn_c2 (s, __a0, __a1)                               \
                  : (((__const char *) (accept))[3] == '\0'                   \
                     ? __strspn_c3 (s, __a0, __a1, __a2)                      \
                     : __builtin_strspn (s, accept))))))                      \
      : __builtin_strspn (s, accept)); })

Is this something you can fix?

Thanks, Ben
