Just to confirm.. when you do size on it, the .text is 4.5 MB and
what was it before?  I trust size. :)

If so, do you see any symbols which indicate subsystems which
are in the new one and not in the old one?

In general, applications should be smaller now.  Maybe not a lot,
but some.  So this is surprising. Debug information should be larger.
Real code should be smaller.

 From here, we will need to:

+ compare map files for surprises
+ look at configuration (e.g. ../configure and your RTEMS configuration)
+how you link
