+// g++ 1.36.1 bug 900210_05
+
+// Section 18.3 of the 2.0 Reference Manual says "An implementation
+// providing { anachronistic features } should also provide a way for
+// the user to ensure that they do not occur in a source file."
+
+// The *only* proper way to "ensure" an absence of anachronstic features
+// is for C++ language processors to generate errors (rather than just
+// warnings) when such features are used. These errors could perhaps be
+// triggered by some set of command line options, or by the absence of
+// certain command line options. (For g++, the -pedantic and -traditional
+// options come to mind.)
+
+// The use of errors rather than warnings is important because errors
+// usually result in non-zero exit status codes for language processors
+// and these non-zero exit stati can be automatically checked during
+// normal execution of a Makefile.
+
+// cfront 2.0 provides the +p option which causes errors to be generated for
+// all cases of anachronistic usage.
+
+// g++ generates neither errors nor warnings for such usage, even when the
+// -ansi and -pedantic options are used.
+
+// Cfront 2.0 passes this test.
+
+// keywords: anachronism, enum types, integral types, implicit type conversions
