Hi,

a few additional easy to fix cases where we thought that a plain error 
was good enough. Tested x86_64-linux.

Thanks, Paolo.

	* decl.c (grok_reference_init): Improve error location.
	(grokdeclarator): Likewise, improve two locations.

/testsuite

	* g++.dg/diagnostic/constexpr2.C: New.
	* g++.dg/diagnostic/ref3.C: Likewise.
