[Boost-users] Boost 1.70 - Test library error on Sun Solaris Studio 12.3

Hi, I'm triying to compile the boost 1.70 on Sun solaris using the version 12.3, but I got an annoying error on the test library: "./boost/test/unit_test_log_formatter.hpp", line 39: Error: Identifier expected instead of "__global". For what I can understand it seems that compiler doesn't recognize the keyword __global. Below, there's the command line that I've used: ./b2 toolset=sun variant=debug address-model=64 threading=multi link=shared runtime-link=shared --with-test Do you have any suggestions? Thanks, Mirko
