Re: [boost] [1.33.0] Partial thaw on branch forfixing theremainingfailures

Problem summary recap:

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.

Unfortunately I don't see the attachment, I've just been testing the fix 
below, that fixes issue (2) above but not (1), if yours does both then that 
would be a lot better obviously :-)

Thanks, John
