Stuck. Found this documentation:

http://www.boost.org/doc/html/bbv2/tutorial/conditions.html

"Sometimes different variant of a target are so different,
that describing them using conditional requirements would
be hard. Imagine that a library has different sources on two
supported toolsets, and dummy implementation for all the other
toolset. We can express this situation using target alternatives:"

lib demangler : dummy_demangler.cpp ;
lib demangler : demangler_gcc.cpp : <toolset>gcc ;
lib demangler : demangler_msvc.cpp : <toolset>msvc ;

I've put this in my Jamfile.v2:

lib libosui : src/dummy.cpp ;
lib libosui : src/dummy.cpp : <toolset>msvc ;
lib libosui : src/dummy.cpp : <toolset>gcc ;

And on OS X I get:

/Users/alan/var/build/boost_1_32_0/tools/build/v2/build/feature.jam:431:
in feature.validate-value-string from module featureerror:
"msvc" is not a known value of feature <toolset>error: legal
values: "darwin"
"gcc"/Users/alan/var/build/boost_1_32_0/tools/build/v2/build/property.jam:249:
in validate1 from module property
.
