I think you got it backwards. Cygwin 1.5 will run pre-1.5 programs with
no problems. It's when you get a program compiled for 1.5 with an older
DLL (e.g., 1.3.22) that you have a problem.
FWIW, setup.ini syntax supports versioned requirements. I don't think
"upset" (the tool that's used to generate setup.ini on the mirrors) does.
Setup itself currently does not support them either, IIRC.
