[boost] [config] Macro proposal

Hi guys, could we please add something like this to the config system? #if defined(__GNUC_PATCHLEVEL__) # define <choose_a_name> ( __GNUC__ * 10000 \ + __GNUC_MINOR__ * 100 \ + __GNUC_PATCHLEVEL__ ) #else # define <choose_a_name> ( __GNUC__ * 10000 \ + __GNUC_MINOR__ * 100) #endif PS: of course it's possible to "share" the common part of the replacement-lists: ( __GNUC__ * 10000 + __GNUC_MINOR__ * 100) or (100 * ( __GNUC__ * 100 + __GNUC_MINOR__)) The decision is up to John :) --Gennaro.
