[Boost-build] Selecting different sources depending on host platform

I have:

alias test : test-cygwin : <toolset>gcc ;
alias test : test-win32 : <toolset>msvc ;

I get this:

warning: toolset gcc initialization: can't find tool g++
warning: initialized from
C:/code/bin/boost-build/build\targets.jam:756: in generate-really from 
module object(main-target)@68
error: failed to build ./test with properties <debug-symbols>on 
<inlining>off <optimization>off <runtime-debugging>on 
<toolset-msvc:version>7.1 <toolset>msvc <variant>debug because no 
best-matching alternative could be found

modules
C:\code\bin\boost-build\kernel\bootstrap.jam:121: in boost-build from module
C:\code\bin\boost-build.jam:6: in module scope from module

I also tried:

alias test : test-cygwin : <os>CYGWIN ;
alias test : test-win32 : <os>NT ;

I get similar log with this too. So how do I get boost-build to select 
alternatives based on the host OS or the toolset -- either one will work for 
me, at least for now...

Thanks,
Emil
