Willy Tarreau 2b080f713f BUILD: compiler: add a default definition for __has_attribute() ... It happens that gcc since 5.x has this macro which is only mentioned once in the doc, associated with __builtin_has_attribute(). Clang had it at least since 3.0. In addition it validates #ifdef when present, so it's easy to detect it. Here we're providing a fallback to another macro __has_attribute_<name> so that it's possible to define that macro to the value 1 for older compilers when the attribute is supported.		2022-11-14 11:14:02 +01:00
