Can anyone help with this, I am trying to get my dual amd mp system to compile 
crafty so that it can use the smp features, but I am having no luck :(

This is the target that is in the make file:

freebsd:
	$(MAKE) target=FreeBSD \
		CC=gcc CXX='$(CC)' \
		CFLAGS='$(CFLAGS) -fomit-frame-pointer -mcpu=i686 -O3 -Wall' \
		CXFLAGS=$(CFLAGS) \
		LDFLAGS=$(LDFLAGS) \
		opt='$(opt) \
		     -DUSE_ASSEMBLY -DFAST -DPOSIX -DSMP -DCPUS=2' \
		asm=X86.o \
		crafty-make


This is final output

gcc -fomit-frame-pointer -mcpu=i686 -O3 -Wall -DUSE_ASSEMBLY -DFAST -DPOSIX 
-DSMP -DCPUS=2 -DFreeBSD -c bench.c
cc -c  -DUSE_ASSEMBLY -DFAST -DPOSIX -DSMP -DCPUS=2 -DFreeBSD egtb.cpp
