two bugs (templates,__alignof__) in egcs (and 2.8.0)

[Ulrich Lauther]

there are two template related bugs in egcs/Linux and 2.8.0 (sparc and Linux *86),
exposed by the code below:

1. When the marked line is uncommented, I get Internal Compiler Error.
this did work ok in 2.7.2.1

2. __alignof__ applied to a template parameter returns 0


----------------- snip ---------------------------


#include <stdio.h>

#define alignof(TYPE) (sizeof(struct{char c; TYPE x;}) - sizeof(TYPE))  


struct C1 {
int foo;
};

template  <class T> 
class Foo {
public:
  Foo() {
    printf("alignof: %d\n",__alignof__(T)); // prints 0, should print 4
    // printf("alignof: %d\n",alignof(T));  // makes compiler crash !!!
  }
};

main() {
  printf("align of C1: %d\n",__alignof__(C1));
  printf("align of C1: %d\n",alignof(C1));
  new Foo<C1>;
}
