I would think it would be a bad idea to compile everything else as 
single-threaded and link against the multi-threaded CRT.  It sounds like 
<threading>single should fail to compile for msvc8.

If someone does that, they should probably also disallow 
<threading>single with <runtime-link>shared, since there's no such CRT 
(AFAIK) in msvc-6 and 7.x
