It doesn't include anything in the way of textual changes to the standards
or details of which syntax productions what new features are supposed to
go in. This means such fundamental information is missing as:
* With context-sensitive keywords, after "typedef int vector;", is vector
a keyword or a typedef?
* With context-sensitive keywords, after "int vector;", is "(vector)+1" to
be interpreted as addition, or a cast (which would seem to parse according
to the syntax, but violate constraints)?
* Do vector literals bind more or less tightly than sizeof? GCC used to
handle compound literals incorrectly in this case
(gcc.c-torture/compile/20010124-1.c).
