[boost] [boost-mpl] -Wall -Werror issue

Hi, This code generates sign / unsigned compare warning with -Wall, could this please be cleaned up? enum { n = # if defined(__EDG_VERSION__) aux::dependent_unsigned<T>::value > -1 # else sizeof(T) > -1 # endif }; It appears that sizeof(T) > -1 yields zero for EDG, Gcc and Clang so perhaps this is just older (unused) code? -- Noel Belcourt
