Commit 8a31aa3 introduces the problem. The patch disallows to dlopen libs without specifying the file extension. This was originally intended by commit df958670 but only worked for paths, not simple filenames. AFAICS this is a more a ruby problem than a Cygwin problem. It tries to dlopen a DLL called "kernel32". But dlopen is POSIX, so it should not assume that an extension is added automatically, just as this isn't done on Linux. Hmm, I'm undecided if this should be fixed in ruby or if we need a Cygwin 2.5.3 reverting this patch...
