In the compiler we have used most (TLD Ada 83, cross from Solaris to
1750A)
there are a couple of compiler switches (-xtra -static_init) that can
be used to eliminate the initialization code, in favour of data placed
in the memory image for direct loading. Works only for _scalar_
variables
though. The same is automatic for all _constants_, as far as I know.
I know that you are using a different compiler, but perhaps a recheck
of the available compiler options would turn up something -- probably
you have already checked.
