* c-decl.c (grokdeclarator): Move warning for qualified void return types with -pedantic to when the function type is constructed. At -W, warn in general for qualified function return types, except for volatile void. * invoke.texi: Document this new warning at -W. testsuite: * gcc.dg/qual-return-1.c, gcc.dg/qual-return-2.c: New tests.
