The executable is built in Cygwin using the command "gcc -static .." and I run it outside Cygwin from a Command Prompt window. The -static switch actually works, in that it reduces the executable's dependencies from cygwin1.dll + several others, to cygwin1.dll alone. The executable is then co-located with cygwin1.dll and together the duo provide me with a portable application. (Actually a fast and elaborate stats package, amazingly compact with exe + cygwin1.dll ~ 3 MB, and fully operable on host machines a million miles from the nearest Cygwin installation.) Typically they reside at the root of a USB stick, but I noticed the reported failure on moving from [1.5] to [1.7]. If I move both files down one or more levels (and it doesn't matter what I name the subdirectory(ies) whether as \bin\ or \anything\else\) then everything works just fine. I'm sure you're right, that it's something to do with where cygwin1.dll [1.7] expects to find itself (cf. [1.5]) and the "cure" is similarly very suggestive of this. I'm dead happy to live with it once I understand it, if only approximately. Thank you very much indeed for your helpful insight, greatly appreciated.
