What about this?

void main(void)
{
     loop:
     if(sp_hitpoints(&current_sprite, -1) < 1)
     {
         itdied();
     }
     //do stuff for movement and seq
     goto loop;
}
void itdied(void)
{
     //play death animation and give exp
     return();
}

EDIT: I don't know if if(sp_hitpoints(&current_sprite, -1) < 1), works. xD
If it doesn't just set a local int to sp_hitpoints and check the variable in the if-statement.
