The CYGWIN variable still exists and is used, if you explicitly set it,
but has never been an indicator of whether a particular .exe was linked
with cygwin or not.

I assume this is your app determining if some other .exe is linked against
cygwin (since you should already know whether your app is a cygwin app).
One way would be using cygcheck to see if the .exe depends on cygwin1.dll.
