I already do something like this (in my case [ glob test_datasets/*.cpp ], but 
if target name is thew same as directory name it will fail to build on linux.

Why do I need to introduce new toolsets? toolset gcc, gcc-4.7, gcc-4.6 already 
works fine. Moreover the main point is to make it work on regression tester box, 
not mine. I need to eliminate failures in regression table. I want to pass std 
option (different one) to compilers which support it and ignore test on 
compilers which do not have it. I can probably get the same result by ifdefing 
the code, but I'd rather have it marked unsupported in regression table instead 
of fake pass.
