Ugh. Multi-line macro. how about #define PUSH_BACK(a,x,t) push_back(a,&x,sizeof(t)) No multi-evaluation problems or other madness. Edit: Actually that won't

Ugh. Multi-line macro. how about #define PUSH_BACK(a,x,t) push_back(a,&x,sizeof(t)) No multi-evaluation problems or other madness. Edit: Actually that won't work for expressions. So #define PUSH_BACK(a,x,t) do { t tmp = x; push_back(a,&tmp,sizeof t) } while(0) slightly better.
