Welcome to Chris's Machine

Does this help? ;-)

It would have been a lot simpler if you just asked: "if you're
stdio buffer size != 1024, please tell me what your machine/OS
is."  Being overly helpful in how the information is retrieved
will just confuse you.  Most System V's have stdio.h's that look
like this - the BUFSIZ's are ifdef'd for various machines.

My BUFSIZ (3b1 3.5.1.4) is really 1024.  V7's are usually 512
and that 4096 you see up there is some flavour of S/370 UNIX.
