So, as I said, I don't know OpenGL. However, if I was debugging this,
I would surely take cygwin entirely out of the mix since you are
building the application with -mno-cygwin and there should be no
reliance on the cygwin DLL at all, contrary to what is showing up
in your error message.
That means I wouldn't run the application from a bash shell. You might
even remove cygwin from the path entirely. If you were desperate, you
could even rename cygwin1.dll to something else temporarily.
