Can we make an exception for this?  The developer insists optimization flags should be turned off just for compiling these parts of the code as defined here in CMakeLists.txt:313-320

set_source_files_properties(
	modules/benchmark/blowfish.c
	modules/benchmark/fftbench.c
	modules/benchmark/md5.c
	modules/benchmark/sha1.c
	PROPERTIES
	COMPILE_FLAGS "-O0 -Wall -Wextra -Werror=implicit-function-declaration"
)

The developer states the reason in modules/benchmark/md5.c:34-36 and in
modules/benchmark/sha1.c:36-38

#if defined(__OPTIMIZE__)
#error You must compile this program without "-O". (Or else the benchmark results may be different!)
#endif

which will cause the program to not compile if optimizations are turned on for this part of the code. I can just remove those 3 lines of code from both modules/benchmark/md5.c and modules/benchmark/sha1.c, and remove the -O0 flag from CMakeLists.txt and it will compile just fine but benchmark results may be different as the developer states.
