Hello again, Alexei, I've commited changes to the CVS (trunk and
release branch) so that C4610 warnings are no longer emitted by MSVC
in level 4 warning mode. I'd appreciate if you could download a CVS
copy (for instance, from http://www.boost-consulting.com/boost.tar.bz2)
and verify that these warnings have actually gone away in MSVC 7.1.
Warnings C4511 and C4512 will continue to appear, though.
