I think this:
+Warn about C++ constructs that may change behavior in the upcoming ISO
C++ standard
would be better as:
Warn about C++ constructs whose meaning differs between ISO C++ 1999 and
ISO C++ 200x.
Similarly:
+Warn about C++ constructs that will change or become obsolete in the
+ISO C++0x standard, e.g., identifiers in C++98 that will become keywords
+in C++0x. This warning is enabled by @option{-Wall}.
would be better with the sentence above as the introductory clause.
OK with that change.
Thanks,
