+# General code to enable approximately all warnings.
+#
+# This is trivial for clang and MSVC, but GCC does not have such an option, and
+# has several esoteric warnings, so we need to enable everything we want
+# explicitly. We enable everything that does not require a value argument,
+# except for warnings that are only relevant for very old languages (earlier
+# than C99 or C++11) or non-standard extensions.
+#
+# Omitted common warnings:
+#
+# Wabi=
+# Waggregate-return
+# Walloc-size-larger-than=BYTES
+# Walloca-larger-than=BYTES
+# Wframe-larger-than=BYTES
+# Wlarger-than=BYTES
+# Wstack-usage=BYTES
+# Wsystem-headers
+# Wtraditional
+# Wtraditional-conversion
+# Wtrampolines
+# Wvla-larger-than=BYTES
+#
+# Omitted C warnings:
+#
+# Wc90-c99-compat
+# Wdeclaration-after-statement
+# Wtraditional
+# Wtraditional-conversion
+#
+# Omitted C++ warnings:
+#
+# Wnamespaces
+# Wtemplates
