commit 1061875d6747f3cb89466aa6df568620a7ddfa05
Author: Stephan Bergmann <sbergman at redhat.com>
Date: Thu Oct 26 21:04:40 2017 +0200
Make loplugin:implicitboolconversion find the same in C++17 and pre-C++17
...see a2d814ac1d7beb6fbe4b9cb7b75814f4b08b8e59
"loplugin:implicitboolconversion" and 24eeb4d286471e4a2103c15efc624a565112ca32
"loplugin:implicitboolconversion" for things previously only found in C++17. As
expected, no further occurrences were found.
