I would like to understand the underlying mechanism. The documentation (FAQ section 4.20) states (as far as I understand) that the Windows path of the Cygwin system root an executable sees is the parent directory of the folder in which the cygwin1.dll resides which is loaded by an executable. As I showed, this doesn't seem to be the case. How does it work then? How is the system root folder passed from parent to child?

Actually if I put cmd in between and clear a few environment variables it works very well in fairly complicated scenarios. Still I would like to understand how the underlying mechanisms work (preferably without reverse engineering).
