Concern: __attribute_pure__ is very similar to __attribute_const__,
which is almost completely, but not totally unlike the keyword
"const"...
Yes, there's also the fact that __pure is a reserved GCC keyword.
Essentially according to GCC docs all of the GCC-specific keywords
are equivalently defined as "keyword", "__keyword", and
"__keyword__", with only the latter two defined in strict-ANSI mode.
The following is valid according to GCC docs:
static int __attribute__((__pure)) my_strlen(const char *str);
With the proposed definition of __pure, that becomes a noticeably
invalid __attribute__((__attribute__((__pure__))))
