Yes, one can always use
#define STR(x) STR2(x)
#define STR2(x) #x
#pragma message( __FILE__ "(" STR(__LINE__) "): warning: " "#warning foo" )
or even
#define BOOST_MESSAGE(msg) message( __FILE__ "(" STR(__LINE__) "): warning:
" "#warning " #msg )
#pragma BOOST_MESSAGE(foo)
but that's not the point, is it. :-)
