[comp.sys.next] Optimization with cc -g set

	Just a follow-up on a thread from last week about the 
c compiler giving better optimization when compiling with 
the symbolic info flag (for the debugger) set, i.e. cc -c -g -O 
because more information was being supplied to the optimizer.

I tried this with the Linpack and Livermore Loops benchmarks and 
observed no noticeable difference in u+s times (~0.5%).
