#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. -- Summary: [4.4/4.5 Regression] stdbool.h/altivec.h Product: gcc Version: 4.4.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: jakub at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40017
