It looks like I should remove the "as it relates to X.Org supported systems" text.

As far as X.Org support, I think it's only relevant as the kernel/uname of
MacOS X.

Again, only relevant to X.Org as the kernel/uname of Solaris and
OpenSolaris-derived systems (including a bunch of community forks/distros).
The original
SunOS (versions 4.x and earlier, before the adoption of the Solaris name)
is no longer supported.

Also, x86_64 is notably the extension of the x86 (i*86) ISA to 64-bits, not
Intel's previous IA-64 architecture used in the Itanium line.

Yes, couldn't say it in a short sentence.

I didn't think it was Cygwin specific. We used "amd64" on Solaris since we
added the 64-bit support (in partnership with AMD, adding some bias) before
Intel had added 64-bit support to their x86 chipsets, since they were relying
on Itanium to be their 64-bit architecture at the time.

The term amd64 is widely used, but is only returned as a uname -m value by a CYGWIN system - if I understand this file correctly!
<PRE>
amd64:CYGWIN*:*:* | x86_64:CYGWIN*:*:*)
echo x86_64-unknown-cygwin
exit ;;

On Solaris, uname -m would return x86_64 but never amd64, right?
