OK, so why does Lattice generate such large programs?  Well, the answer
is simple, and it sux having to deal with it by going around it, but...

As far as I've seen, Lattice on the Amiga is a simple port of Lattice on
the PC.  Lattice prides themselves on the fact that they have all this
portable stuff (I prefer libraries customized for the target machine, but
when you want portability...).  Lattice 'C' on the PC has the same problem
with huge libraries.

The cause is in their c.c, or startup.obj module.  You see, they call exit()
after the user main() returns, and exit() references a lot of other library
routines that get dragged in and waste space.  After using Manx for 5 months,
I would bet that Lattice's code generation can't be any worse than the
code generated with Manx's +L option.  If some adventuresome soul wants to
try and do something about it, there is a #define that Lattice uses in c.c
called TINYMAIN, which is supposed to make smaller programs, but I'm pretty
sure that even with TINYMAIN, exit() is called and programs are still
inflated with a bunch of junk that is not needed.  I hear that by mucking
with c.c, it is possible to get decent sized compiled programs, but I have
not spent the time to see what it would take on the Amiga version of Lattice.

Good luck!
