// gcc2Attributes.h - force-included into every gcc 2.95 compile by
|
|
// make/support/be/gcc2.sh. JoeyLib's sources use three GCC attributes that
|
|
// came with gcc 3.1 and 3.3, which gcc 2.95 would warn away (and -Werror
|
|
// stop). Each name becomes __unused__, an attribute gcc 2.95 knows and that
|
|
// changes nothing here (an empty name would leave an empty slot in the
|
|
// attribute list, which crashes gcc 2.95). Nothing is lost: gcc 2.95
|
|
// inlines no differently for them, and strict aliasing, which may_alias
|
|
// guards against, is off for every gcc 2.95 compile.
