+# Add all warning flags we can.
+add_flag -Wall
+add_flag -Wextra
+add_flag -Weverything
+
+# Disable specific warning flags for both C and C++.
+
+# TODO(iphydf): Clean these up. Probably all of these are actual bugs.
+add_flag -Wno-cast-align
+# Very verbose, not very useful. This warns about things like int -> uint
+# conversions that change sign without a cast and narrowing conversions.
+add_flag -Wno-conversion
+# TODO(iphydf): Check enum values when received from the user, then assume
+# correctness and remove this suppression.
+add_flag -Wno-covered-switch-default
+# Due to clang's tolower() macro being recursive
+# https://github.com/TokTok/c-toxcore/pull/481
+add_flag -Wno-disabled-macro-expansion
+# We don't put __attribute__ on the public API.
+add_flag -Wno-documentation-deprecated-sync
+# Bootstrap daemon does this.
+add_flag -Wno-format-nonliteral
+# struct Foo foo = {0}; is a common idiom.
+add_flag -Wno-missing-field-initializers
+# Useful sometimes, but we accept padding in structs for clarity.
+# Reordering fields to avoid padding will reduce readability.
+add_flag -Wno-padded
+# This warns on things like _XOPEN_SOURCE, which we currently need (we
+# probably won't need these in the future).
+add_flag -Wno-reserved-id-macro
+# TODO(iphydf): Clean these up. They are likely not bugs, but still
+# potential issues and probably confusing.
+add_flag -Wno-sign-compare
+# Our use of mutexes results in a false positive, see 1bbe446.
+add_flag -Wno-thread-safety-analysis
+# File transfer code has this.
+add_flag -Wno-type-limits
+# Callbacks often don't use all their parameters.
+add_flag -Wno-unused-parameter
+# libvpx uses __attribute__((unused)) for "potentially unused" static
+# functions to avoid unused static function warnings.
+add_flag -Wno-used-but-marked-unused
+# We use variable length arrays a lot.
+add_flag -Wno-vla
+
+# Disable specific warning flags for C++.
+
+# Comma at end of enum is supported everywhere we run.
+add_cxx_flag -Wno-c++98-compat-pedantic
+# TODO(iphydf): Stop using flexible array members.
+add_cxx_flag -Wno-c99-extensions
+# We're C-compatible, so use C style casts.
+add_cxx_flag -Wno-old-style-cast
+
+# Downgrade to warning so we still see it.
