[v2] searched-lib and msvc (Unused source target) (fwd)

Hi. I've been experimenting with Boost.Build.v2 for a project of mine and
having trouble with searched-lib. Here is a simple test that I built:

toplevel/
project-root.jam
----
| import msvc ;
----
boost-build.jam
----
| boost-build ../tools/boost.build ; # V2 is here!
----
Jamfile
----
| project top;
| build-project sub ;
----
sub/
main.cpp
Jamfile
----
| project sub ;
| lib openssl : : <name>libeay32 <search>c:/openssl/lib ;
| exe main : main.cpp openssl ;
----
(Note 1: I'm using link=static)
(Note 2: For this test, I don't care about including the openssl headers.)
A similar arrangement works find with gcc/freebsd but fails with
msvc/win32, msvc/cygwin and gcc/cygwin for different reasons, as follows:
gcc/cygwin:
c:/openssl/lib is not reconized as an absolute path (the command
line ends up containing: -Lsub/c:/openssl/lib). I can easily work around
this one by using /cygdrive/c/openssl/lib.
msvc/cygwin:
error: Unknown target type RSP. I don't really care about this one
yet.
msvc/win32:
warning: Unused source target { openssl.SEARCHED_LIB }
Main target is subbug/main
This is the one case I care so I went looking for reasons and fixes
with no luck. I notice that SEARCHED_LIB cannot be consumed into a RSP so
I added it to the NT specific section about RSPs. That didn't work because
searched-lib-target has no name (or a related error, can't remember).
I'd be glad to do some experiments and try fixes if someone can give
guidance.
Best regards,
