BOOST_RATIO_STATIC_ASSERT: constant "X" is not a type name

[kindr@…]

Whily compiling a code with icc that uses boost, I get this error:

/home/ac/sroy8/boost_1_52_0/boost/ratio/detail/overflow_helpers.hpp(77): error: constant "X" is not a type name

BOOST_RATIO_STATIC_ASSERT(X <= max - Y , BOOST_RATIO_OVERFLOW_IN_ADD, ());
