If you complete the quote with the later comment suffix
	"... on Windows 2008 and 2012"
that may have been true on server installs five or ten years ago, almost half
Cygwin's history, but Cygwin 64 bit has come a long way in that time, as has
Windows 64 itself, Cygwin Windows server support, and the Cygwin 64 bit packages
supported.
Many of us with 64 bit machines and OSes have been running Cygwin 64 bit since
the Cygwin packages we needed became available on Cygwin 64 bit.
Nowadays, you should install the Cygwin arch matching your OS, and Cygwin 64 bit
is recommended if you need to install a lot of packages with DLLs, e.g. X Window
System, especially if you want to run full Gnome or KDE desktops, with many apps
and many dependencies on library packages.

Cygwin 32 bit and setup-x86 will not work on Windows 64 bit server (2008R2 and
newer) that no longer have 32 bit WoW subsystem support.
You may be unable to set up to run a lot of apps with many dependencies on
libraries in the available address space.
