Conditional sources?

Here's a simple question...can I do "Conditional Sources" using the same
syntax as Conditional Properties?

I.e.

lib mylib : foo.cxx bar.cxx <os>NT:ntbase.cxx ;

expressing that the file "ntbase.cxx" is compiled in only on the NT OS?

Or do I have to do something more convoluted like the following?

Sources = foo.cxx bar.cxx ;
if [ os.name ] = NT 
{
Sources += ntbase.cxx ;
}
lib mylib : $(Sources) ;
