My sense would be to revert these changes and eliminate the target stucture

Well certainly it would be useful to have precise measurements of the
impact. Closer to home (if home is GNAT) debug.ads/adb do not make the
debug flags constant in GNAT, so that they can be changed with -gnatd?
and as far as I know we never measured the impact of this similar kind
of issue -- we should :-)
Certain of the GNAT -gnatd switches are user important (like -gnatdO
probably), but most are not.
