/*
* _Bool bit-fields: C99: 6.7.2.1, paragraph 3 along with Defect Report 335.
* _Bool bit-fields of size up to CHAR_BIT must be supported.
*/
#include <limits.h> /* CHAR_BIT */
int main(void){
struct bits {
int : 0;
_Bool : 0; /* force alignment */
_Bool bbf1 : 1; /* holds values 0 and 1 */
_Bool bbf8 : CHAR_BIT; /* must be supported */
} bits;
return 0;
}
The above code fails to compile in gcc 4.3.2-7
The error message is:
error: width of 'bbf8' exceeds its type
A _Bool is one storage unit, so is CHAR_BIT bits.
Therefore, _Bool bit-fields of size 0, 1, 2, ... CHAR_BIT
must be supported.
