John Apa said "Yes, but has anyone seen an ISO C++ compliant compiler without any special "features"? I certainly haven't, gcc is probably the closest thing." He might as well have ended the sentence after "compliant compiler". As far as I can tell (using the Plum Hall test suites as a measure), there are no ISO compliant C++ compilers -- neither the core language nor the standard libraries. Phil Philip W.
