Documentation reads otherwise and it only mentions possible cons in =20 one section? # CFLAGS controls the compiler settings used when compiling C code. # Note that optimization settings other than -O and -O2 are not recommended # or supported for compiling the world or the kernel - please revert any # nonstandard optimization settings to "-O" or "-O2 -fno-strict-aliasing" # before submitting bug reports without patches to the developers.
