With gnat-gpl-2006 on Mac OS X I get eg

   $ gnatmake -g -gnat05 dbprog -f -gnatyXgcc -c -g -gnat05 -gnatyX dbprog.adb
   gnat1: bad -gnaty switch (invalid style switch:X)
   gnatmake: "dbprog.adb" compilation error

which is different .. yes, 4.0.0 says

   $ GNAT_PREFIX=/opt/4.0.0 gnatmake -g -gnat05 dbprog -f -gnatyX
   gcc -c -g -gnat05 -gnatyX dbprog.adb
   gnat1: invalid switch: y
   gnatmake: "dbprog.adb" compilation error

but you ought to be using it for your own software. Much easier,
though, to just say -gnaty and be done with it! So what if your lines
are restricted to 79 characters, I say, with any luck you can get 2
editor windows side-by-side and see even more code at once ..

That A in the original set looks odd. Try gnatmake -h to see your
legal set.

-gnatwae turns on most optional warnings (good) and treats them as
 errors (harsh).
