No, seeing that this is C++ and the include path has "." in it, I suspect there's an executable with the same name as an "include <…>" in the cwd. Cygwin helpfully ignores the .exe suffix on the executable in certain cases, why it does that here I don't know, maybe try if that changes with an earlier Cygwin DLL?
