/* Test for _Bool bit-fields. After TC2, the width of a _Bool bit-field must not extend the width (number of sign and value bits) of _Bool, which is implementation-defined but is 1 unless the implementation defines representations for values greater than 1 in type _Bool and allows for _Bool objects to have such types, which GCC does not. */ /* Origin: Joseph Myers */ /* { dg-do compile } */ /* { dg-options "-std=iso9899:1999 -pedantic-errors" } */ struct foo { _Bool b : 2; /* { dg-error "width" } */ };
