I'm also trying to use GNU CC for architectural studies.

Can you give me slightly more explicit mail addresses for yourself and
Alex? elh@vu-vlsi and alex@umbc3 are missing a few components (I assume
.edu. but what then?)

Also, would it be possible to obtain some of your benchmarks? 
Many of them are unfamiliar to me:

	tst.sh 
	multi.sh 1    
	multi.sh 1 2   
	multi.sh 1 2 3  
	multi.sh 1 2 3 4 
	multi.sh 1 2 3 4 5
	dwrite
	dread
	fcalla
	fcalle
	fibo
	float
	iofile
	loop
	pipes
	scall
	sieve		-- Probably have a version of this
	bytesort
	iocall		-- This is Jan Stubbs'
	dryr		-- Have this
	drynr		-- Have this
