Only in very limited cases: (1) we're talking about cygwin-1.7.x (2) Either (a) only one of those parallel instances is in use at a time, including installed services, or (b) all of those parallel instances have exactly the same version of the DLL (3) Even so, doing this is not officially supported (the current dual-installation "support" vis-a-vis cygwin-1.5.x and cygwin-1.7.x is (a) temporary and (b) intended for package maintainers only, in order to prepare the cygwin-1.7 packages -- and package maintainers generally know what they are doing and what the pitfalls of a dual/multiple installation are. Right? You still have to worry about the shared memory region name, and its format which may vary with DLL version. Plus there still might be other stuff that prevents parallel cygwin installs from running simultaneously. And I don't think supporting simultaneous use of multiple cygwin installations is one of our goals, is it? -- Chuck
