Set PATH appropriately. There is also one registry setting that Cygwin
and GNAT fight over; 

HKEY_LOCAL_MACHINE\SOFTWARE\Free Software Foundation

The simplest way to manage this is to use the Registry Editor to
export this key (to a .reg file) after installing Cygwin, and again
after installing GNAT. Then run the appropriate .reg file when you
need to run the compiler.

This use of the registry is totally inappropriate, as far as I can
tell. It just gets in the way.

You can set PATH and run the .reg file from a batch script; that
simplifies things a bit.
