From 667335a42d683f73ec9c52c68730041d83a163a5 Mon Sep 17 00:00:00 2001 From: Uri Simchoni Date: Mon, 20 Nov 2017 20:53:12 +0000 Subject: [PATCH] build: ensure compiler flags are properly detected While checking for compiler flag availability, treat warnings as errors. Thus if the compiler only warns about unsupported flag, it will fail the test and the flag shall be marked as unsupported.
