Peter,

I ended up using CVS from the command line. That brought back a few
memories.

I had to change
        std::printf	to	printf
        std::clock	to	clock
and
        add { and } around the second "    for(int i = 0; i < m; ++i)"
so I saved it as Gshared_ptr_mt_test.cpp
I compiled with 
        cl -GX -MD 
And ran it as follows:

Z:\geoff\boost\libs\smart_ptr>Gshared_ptr_mt_test.exe

"It" is libs/smart_ptr/shared_ptr_mt_test.cpp in the CVS (you need to update
shared_ptr from the CVS, too). Thanks in advance.
