I have both the GNAT 3.13p compiler and a Cygnus compiler installed.
There is one only thing you must not forget: Whichever compiler you want
to use, put it at the front of the PATH. I have Cygnus GCC at the front
of the PATH. If I want to use GNAT, I have to do

SET PATH=D:\ADA\GNAT\BIN;%PATH% or
export PATH=//d/Ada/GNAT/bin:$PATH

depending on which shell I happen to use. Everything is working fine
then :-)
