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.

s/familly/family/

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.

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.
