I've often wished that __attribute__s would behave like CV-quals:
char * const ptr;
== const pointer to char
struct entrystruct * __attribute__ ((packed)) entry;
== packed pointer to struct
char const * ptr;
== pointer to const char
struct entrystruct __attribute__ ((packed)) * entry;
== pointer to packed struct
I haven't done an exhaustive survey of attributes, but I know it doesn't
work that way for section attributes, and there have been times when I would
have liked it to.
