sedit and a Makefile

[Dennis Veatch]

I'm trying to create a module called toolame (optimized mpeg 2 encode). The 
source doesn't have a "configure" just a Makefile. 

I think I have a handle on using sed but...... I want the Makefile to use the 
lunar optimizations instead of those in the Makefile. The defaults in it 
right now are ;

CC = gcc
OPTIM = -O3
REQUIRED = -DNDEBUG -DINLINE=inline
ARCH = -march=pentium
PG = -fomit-frame-pointer

and has this line that ties them altogether ; 

CC_SWITCHES = $(OPTIM) $(REQUIRED) $(ARCH) $(PG) $(TWEAKS) $(WARNINGS) 
$(NEW_02L_FIXES)

So I guess the question is, how to substitute those in the BUILD file.
