Sorry ... C does NOT require ASCII.  I suggest you read the C Reference
manual *real*closely* sometime(in the rear of K&R).  It talks about
C compilers for many different machines.  Including IBM-370's.
Also, '\n' does not mean ASCII LF.  It means, "whatever is used
as a line seperator".  I know of 2 C compilers where it means something
else.

Like somebody else said in the quoted posting (I editted it out).
You can write a BAD compiler, or you can write a good compiler.
If you're comparing the DECUS C compiler to (fr instance) OMSI pascal,
the pascal compiler will of course come out worse.
