If the compiled program does a shift by a negative amount, combine will

least).

The resolution of C11 DR#423, apart from doing things with the types
of expressions cast to qualified types which are only in standard
terms observable with _Generic and which agree with how GCC has
implemented _Generic all along, also specifies that qualifiers are
discarded from function return types: "derived-declarator-type-list
function returning T" becomes "derived-declarator-type-list function
returning the unqualified version of T" in the rules giving types for
function declarators.  This means that declarations of a function with
both qualified and unqualified return types are now compatible,
similar to how different declarations can vary in whether a function
argument is declared with a qualifier or unqualified type.

This patch implements this resolution.  Since the motivation for the
change was _Generic, the resolution is restricted to C11 mode; there's
no reason to consider there to be a defect in this regard in older
standard versions.  Some less-obvious issues are handled as follows:

* As usual, and as with function arguments, _Atomic is not considered
  a qualifier for this purpose; that is, function declarations must
  agree regarding whether the return type is atomic.

* By 6.9.1#2, a function definition cannot return qualified void.  But
  with this change, specifying "const void" in the declaration
  produces the type "function returning void", which is perfectly
  valid, so "const void f (void) {}" is no longer an error.

* The application to restrict is less clear.  The way I am
  interpreting it in this patch is that "unqualified version of T" is
  not valid if T is not valid, as in the case where T is a
  restrict-qualified version of a type that cannot be restrict
  qualified (non-pointer, or pointer-to-function).  But it's possible
  to argue the other way from the wording.

Bootstrapped with no regressions on x86_64-pc-linux-gnu.

	* c-decl.c (grokdeclarator): For C11, discard qualifiers on
	function return type.
