It gets worse.  In our environment, we have three BUFSIZ's
to contend with: 4096 on our MIPS 2030s, 2048 on the Targon/35s
(Pyramid 90x in other clothes), and 1024 on everything else
(five other machine/OS types).  I wouldn't be surprised if something like
UNICOS uses something even bigger (8192 or even 16384).

512 is likely to the rarest of the lot.  There aren't many V7s around.
