Check if a C compiler warning is supported by clang/gcc
# Detect if a warning flag is supported by the $(CC) compiler

# HEADS UP- This should be used after including CppUTest MakefileWorker.mk,
# which populates the $(COMPILER_NAME) variable, but will work if you don't
# (it's just slower by a few ms because it will attempt to use the wrong
# option when testing).

# Example usage:
# ifeq ($(call WARNING_SUPPORTED,address-of-packed-member),supported)
# CPPUTEST_ADDITIONAL_CPPFLAGS += \
