Hi,

some additional straightforward bits in typeck.c, which I noticed when I 
went through the cp_build_binary_op callers. Tested x86_64-linux.

Thanks, Paolo.

	* typeck.c (cp_build_modify_expr): Prefer error + inform to
	error + error in one place.
	(get_delta_difference_1): Likewise.
	(get_delta_difference): Likewise, in two places.

/testsuite
2019-10-24  Paolo Carlini  <paolo.carlini@oracle.com>

	* g++.dg/conversion/ptrmem2.C: Adjust for error + inform.
	* g++.dg/gomp/tpl-atomic-2.C: Likewise.
