[boost] BOOST_TESTED_AT

From: Giovanni Bajo (giovannibajo_at_[hidden])

Hello,

the argument of BOOST_TESTED_AT() is not evaluated until
BOOST_DETECT_OUTDATED_WORKAROUNDS is defined. While this is not such a big
problem, it hides typos.
I propose this little patch, but I don't know how well it will interact with
broken preprocessors.

Comments?
