I'd like to make sure I understand the issue. Please correct me if I'm

The implementation doesn't contain <cwhatever> headers. Boost uses
<cwhatever> headers.

The problem can be hacked around by #include <whatever.h> and then doing
the usual namespace std { using ::somename; ... } trick.

There are two places to apply this hack:

   1) Do it in the boost headers at the point of the original #include,
controlled by #ifdef's. Downside: messes up the boost headers. Has to be
applied in every new boost header, as they are added. Although because of
the Microsoft almost-C++ compiler, the namespace part of the trick has to
be done anyhow.

   2) Provide a set of dummy <cwhatever> headers, containing the
hack. Users would presumably include these headers in their search path
only if their standard library implementation didn't supply the <cwhatever>
headers. Downside: it might appear boost was blessing these broken

Is this a correct analysis?
