It is possible to put an expression to calculate the 3000000 in this case into a
macro:
#define BOOST_VERSION(major,minor,patchlvl) \
(major * 1000000 + minor * 1000 + patchlvl)
#define BOOST_GCC \
BOOST_GCC_VERSION(__GNUC__,__GNUC_MINOR__,__GNUC_PATCHLEVEL__)
Example:
#if BOOST_WORKAROUND(BOOST_GCC,< BOOST_VERSION(3,2,3))
// ...
#endif
