Same result (system.ads and rep*.adb were in gcc/, but even moving them
to $builddir and using -I. doesn't work).  Same result == testcase passes.

Maybe I have to rebuild gnat1 using that modified system.ads?  Even
when I change the master copy in gcc/ada/rts/ the error does not reproduce
for me.  But I have not re-built gnat1 for quite some time beacuse of the
errors that I should recompile stuff.
