glibc still has:
# 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)); })
The lone 0 in the middle should be explicitly cast to size_t, like it is for
fread_unlocked. Could you report it to glibc please?
gcc could avoid this warning when converting a constant, I am pretty sure the
same issue (possibly with another macro) already led to such a conversation...
