32 and 64 bit cygwin on same machine?

[Dominic Herity]

I'm using Python and Cygwin to test a 32 bit Windows dll.
Now I need to test a 64 bit build of the same dll.
Can I install 32 bit and 64 bit Cygwin on the same machine and choose
to run either 32 bit or 64 bit python to test the corresponding dll?
Or do I need to keep them on separate machines?

Thanks
Dominic
