Hmmm, my gcc/ada/Makefile doesn't have a reference to target_alias:

% grep target_alias Makefile
% grep target= Makefile
target=hppa1.1-hp-hpux10.20

Quite possible -- that stuff has changed a lot recently.

Maybe that's why I don't have target_alias in the generated Makefile :-)

Yes, the lack of prefix & transform name will be an issue we'll
have to settle.  Part of the generic "fix Ada for cross platforms"
problem.

It should be noted that once I got the first egcs based gnat binary running
it would successfully bootstrap with -O2 or no optimization -- no released
version of gnat can do that as far as I know! (some ada files have to be built
with optimization and others without)

Many of the PA gnat problems can be traced back to Kenner refusing to
fix some C code in the Ada front end which has undefined ANSI behavior.

:-) :-)  It certainly seems slow to me :-)
