[Bug target/40017] New: [4.4/4.5 Regression] stdbool.h/altivec.h

[jakub at gcc dot gnu dot org]

#include <stdbool.h>
#include <altivec.h>

vector bool int b;

int
main (void)
{
  return 0;
}

used to compile up to 4.3, doesn't any longer.  I wonder what can be done here
though, for C++ with the conditional macros bool keywords can coexist well with
the context sensitive keywords, but unfortunately #define bool _Bool
kills the conditional keyword behavior.

I'd say handling _Bool the same way as bool after vector would be a good idea.
It has a disadvantage that in addition to the (I'd say desirable):
#include <stdbool.h>
#include <altivec.h>
...
vector bool int i;
also
vector _Bool int i;
would be accepted, but the advantages IMHO outweight disadvantages.

Yes that seems like the right idea; the altivec specs was written before C99
was out.

_Bool would need to be a conditional macro too though, I wonder if some ISO C99
pedantry can't test that _Bool isn't defined or something like that.
But then for C++ it is similar with defined(bool) also being true with
-maltivec instead of false.
