I believe I have an idea what's happening here, in the Jamfile you have:

        <runtime-link>static
        <threading>single

as build requirements, but vc8 does not have a single threaded runtime at 
all, and I think it's this that's messing up the build system and the auto 
linking code, let me try and explain:

1) Setting <runtime-link>static <threading>single causes bjam to mangle the 
lib name with "-sgd" for the debug build, but it should actually be mangling 
the name with "-mt-sgd" because there is no single threaded option, so we're 
really building a multithread lib.
2) Setting <runtime-link>static <threading>single causes bjam to build with 
/MLd, but that option isn't actually recognised by VC8, so it reverts to the 
default which appears to be /MT - this is why the auto-link code is trying 
to link against the "-mt-s" build variant - bjam isn't actually building the 
variant it thinks it is.

If we're serious about VC8 being a release requirement, then we really 
should fix the build system to handle it correctly,

John.
