Subject: [PATCH] re PR ipa/92421 (ICE in inline_small_functions, at
 ipa-inline.c:2001 since r277759)

	PR ipa/92421
	* g++.dg/torture/pr92421.C: Add -Wno-return-type to
	dg-additional-options.  Avoid -Wwrite-string warnings, most of
	-Wreturn-type warnings, define bf ctor.  Use struct instead of class
	with public: at the start.
