And yet another: 
- you build project from one directory
- you change to different directory and remove an executable
- you rebuild -- bjam thinks rsp is up to date, so it reuses it. Alas, path 
names in rsp are no longer correct.

/me think that rsp file should be created as part of msvc.link action, and 
those problems will disappear. I.e. msvc.link is marked as producing EXE and 
RSP and msvc.link rule creates RSP and then invokes linker. In this case, rsp 
will be always recreated when needed.
