Could be. Although I find it weird that the boostcpp module has 
recursive configuration checks. Because if it is.. It should really 
not do that.
No idea about that. It only fails with Cygwin GCC though.
Interesting.. That's the one setup I don't test :-(
Even more interesting, it works with Cygwin Clang (toolset=clang). Only 
toolset=gcc fails.

C:\boost-git\develop\libs\config\test>b2 print_config_info toolset=clang
