The cited Web page mentioned, off-hand, that Linux is "probably" a
prerequisite.  The compiler README says, more specifically:

"I only tested for Redhat Linux 4.2 (linux kernel 2.0.30) on Intel
x86's.  I don't see much reason for it to care what Unix OS you have
(must have signals, printf, syslog, and ... ?), but it definitely
won't do anything for non x86 as only x86 instructions are emitted for
canaries.  The canary library is architecture independant [sic], but might
be more sensitive to OS."

Canaries, for those who didn't get the joke, are explained further in
the README.  The practice was hardly limited to the Welsh - it was done
widely here in the States, too.  [Welch is a grape products company, or
something cads do with responsibilities, folks!]
