Well, for an installation that old it would probably be quite helpful if
you did a clean fresh install. A 32bit Windows can deal just fine with
4GB of memory (not so much with larger memory), you can make about 3GB
of that available to user processes with a boot option (at the expense
of memory reserved for the kernel space).

You can keep using a 32bit Cygwin on any Windows 64bit desktop version
in existence so far, they all come with the WoW64 subsystem that is
necessary to run 32bit Windows applications.

However, I'd still recommend you make the switch to a 64bit Cygwin if
you have the option.
