You're right that cygwin shell tries to emulate bash, I just twisted things.

The problem is that in unix executables don't have extension but they actually do in cygwin so I think that's the root of the problem.

Probably compiling binaries under cygwin without the exe extension, like unix, is not an alternative, or is it? Cygwin may detect if it is executable checking if it's PE format; if it is perl script.  Just check if file is present in path or run. /file
