It doesn't happend with the gcc releases prior to 3.x, and other compilers (Borland C++, Visual C++, Metrowerks CodeWarrior) don't issue this warning. I'm not really sure if this is a bug, but, if not, can you say me what's wrong ? Thanks ! --- Begin of dummy.cpp source file --- namespace n { int i; } #define M(a) a##i int main( void ) { M(n::) = 42; // The line which produces the preprocessor warning. return 0; } --- End of dummy.cpp source file --- >How-To-Repeat: g++ dummy.cpp >Fix: >Release-Note: >Audit-Trail: >Unformatted:
