Quite possible, I use gnat on a regular basis from my bash shell.

The problem is that CygWin's gcc doesn't know about Ada  ("gcc.exe: language
ada not recognized" may be familiar).  The solution is to ensure that
gnat/bin or gnatpro/bin occurs before /bin in your path variable.

For example, my .bashrc contains the incantation "PATH=/c/gnatpro/bin:$PATH"
which does the trick.  Alternatively, editing cygwin.bat to say "SET
PATH=C:\gnatpro\bin;f:\bin;f:\usr\local\bin;%PATH%"  would do precisely the
same.
