And, it also has if (pragma_lex (&x) !=3D CPP_EOF) warning (OPT_Wpragmas, "junk at end of %<#pragma pack%>"); message at the end in case one uses #pragma message 4 or #pragma message "foo" 4 etc. I think #pragma GCC {warning,error} can stay where it is, but it would be n= ice if it behaved the same way.=
