Package: src:gcc-7 Version: 7.1.0-6 Severity: important This looks to be a change introduced in 7.1.0-6 (or at least triggered by). Is it intended that dpkg-buildflags calls are now in the ada patches? I would better like these in the packaging, rather in the upstream code. Only saw that because apparently libada cannot be built with -O3 (at least on ppc64el). See PR80867 for that.
I'm working around that by forcing a -O2 libada build for now.
