[gnu.gcc] Need help with gcc constructors

brennan@rtp.dg.com (Dave Brennan) (01/22/90)

In the following code segment, I don't understand why gcc complains
"invalid lvalue in unary `&'" about the "trash" initilization but has no
problem with the "junk" initialization.  I invoked the compiler 
"gcc -g -c trial.c"   Can somebody enlighten me here?  Thanks.


typedef enum { 
  enum_1,     
  enum_2   
} tag_t;

typedef struct {
  tag_t type;
  char *class_data;
} BAZ_T;

extern int foo();
extern char *bar;

main()
{
  char *junk = (char *) & (BAZ_T) { enum_1, (char *) foo };
  char *trash = (char *) & (BAZ_T) { enum_2, (char *) bar };
}
