yes, now it runs again without a flaw.

they've disappeared.

I changed in the Makefile.Darwin to:

compilerOptFlags := -O -O1 -O2 -O3 -O4 -O5 -O6

ifeq ($(OptLevel),-O)
    OPTFLAG = -O6
else
    OPTFLAG = $(OptLevel)
endif

ifneq (,$(filter $(compilerOptFlags),$(OptLevel)))
    # If any optimization flag occurs then:
    CXXFLAGS += -DNDEBUG
endif

copying part of the LINUX-Makefile over.

shouldn\t this take care of it?

greeting!
