One thing I noticed is that GNAT doesn't see a change to the
environment variables as triggering a recompilation (well, there may
be more flags):

$ gnatmake -Pfools fools-main
gcc -c -gnateDDUMB=3D"Fool" -I- -gnatA /Users/simon/tmp/target/fools-
main.adb
gcc -c -gnateDDUMB=3D"Fool" -I- -gnatA /Users/simon/tmp/target/fools.ads
gnatbind -I- -x /Users/simon/tmp/target/fools-main.ali
gnatlink /Users/simon/tmp/target/fools-main.ali -o /Users/simon/tmp/
target/fools-main
$
$ gnatmake -Pfools -XDUMB=3D"\"Idiot\"" fools-main
gnatmake: "/Users/simon/tmp/target/fools-main" up to date.
