(You mean the cat editor? :-) )

Actually, I prefer

	/lib/cpp | /lib/ccom | /lib/c2 | as -o foo.o

but this does not work on Suns.  Most often, though, a simple

	/lib/ccom

or if you need to see what the optimiser does,

	/lib/ccom | /lib/c2

suffices to test `features' like this one in the Sun compilers:

	f(){register char c= -1;register i;
	i=(int)(char)c;i=(int)(char)-1;i=(int)(char)(int)-1;}

which puts the values -1, 255, and -1 (respectively) into i.
