I think everyone should be able to write something like this:
lib postgres : : <file>Lib/win32/vc7/libpqdll.lib <toolset>msvc ;
lib postgres : : <name>pq <toolset>gcc ;
and compile it on windows machine. Now it is posible coz gcc.jam
doesn't stops with error when no gcc found. But msvc.jam does it. I think
this is wrong.

Done. See attach file in post to Vladimir.
