+This is a collection of things that test suites have
+said were "wrong" with GCC--but that I don't agree with.
+
+First, test suites sometimes test for compatibility with
+traditional C. GCC with -traditional is not completely
+compatible with traditional C, and in some ways I think it
+should not be.
+
+* K&R C allowed \x to appear in a string literal (or character
+literal?) even in cases where it is *not* followed by a sequence of
+hex digits. I'm not convinced this is desirable.
+
+* K&R compilers allow comments to cross over an inclusion boundary (i.e.
+started in an include file and ended in the including file).
+I think this would be quite ugly and can't imagine it could
+be needed.
+
+Sometimes tests disagree with GCC's interpretation of the ANSI standard.
+
+* One test claims that this function should return 1.
+
+ enum {A, B} foo;
+
+ func (enum {B, A} arg)
+ {
+ return B;
+ }
+
+I think it should return 0, because the definition of B that
+applies is the one in func.
+
+* Some tests report failure when the compiler does not produce
+an error message for a certain program.
+
+ANSI C requires a "diagnostic" message for certain kinds of invalid
+programs, but a warning counts as a diagnostic. If GCC produces
+a warning but not an error, that is correct ANSI support.
+When test suites call this "failure", the tests are broken.
