commit d72b33214a2cd398b34a921500abc0c5e4968be1 Author: Guillem Jover <[email protected]> Date: Sun Sep 4 17:17:15 2016 +0200 build: Check the availability of -Wpositive variant instead of -Wno-positive At least gcc and clang do not warn on -Wno-* warning flags, only when something else needs to be reported, which defeats our test. In those cases pass an additional argument that will be what we will actually check, but not use afterwards. --- debian/changelog | 3 +++ m4/dpkg-compiler.m4 | 12 ++++++++---- 2 files changed, 11 insertions(+), 4 deletions(-) diff --git a/debian/changelog b/debian/changelog index a98cc68..7f86c99 100644 --- a/debian/changelog +++ b/debian/changelog @@ -12,6 +12,9 @@ dpkg (1.18.11) UNRELEASED; urgency=medium mode (not used in Debian).
