Actually, I hate the fact that -mdynamic-no-pic covers up this problem, 
but, that flag is good to use anyway (for all program compiles, not for 
any shared library code, or code that might go into a shared library).

We did this locally, by putting:

# APPLE LOCAL -mdynamic-no-pic for host programs for speed
XCFLAGS = -mdynamic-no-pic

into config/rs6000/x-darwin

and arranging for that to be used.  You can try that solution out and 
see if it works for you in the Ada world...


A better solution, would be to autoconf this, as older compilers do not 
have this flag.  Though, I've been having my doubts that autoconf is a 
saviour.  When bootstrap speeds 98%+ of the time in /bin/sh, I think 
we've done something wrong, and we are well on our way to achieving 
that goal.
