I have added a version of the remove_xxx metafunctions that works with
MSVC6.5 and VC7.0 for all types without any sort of registration
(using the new typeof functionality mentioned above)

http://boost-sandbox.sourceforge.net/vault/, remove_xxx.zip.

The relevant tests under lib/type_traits/test/ compile succesfully.
(remove_xxx_test.cpp)

Since the implementation of typeof for VC relies on compile time
constants in order to work , there is a limitation of how many
different types the typeof operation can be used to infer in a single
cpp-file. Typically around 2500. Hopefully, this is not a major
problem.
