I have a compiler I wrote under UNIX, that uses code generated
by YACC and LEX.  Therefore,
there are a good chunk of glabal data arrays (initialized).  I want
to get his working on the MACIIx.

I have a MACIIx with 8 bloddy megabytes of memory, and it seems that I
can't access it.  I have plenty of functions and they have to go thru
this "jump table".

Please exuse my ignorance of this Mac.  However, my SUN is a 68030 and
I can access all kinds of data.  With the MPW software, I can't even get
past the Linker.  Global data size exceeds 32K.  That seems to be a problem
but I'm not sure if it is the root of it.

Now, I've read the manuals
and all that stuff and I believe I've selected the right options for 32-bit
addressing. I've played around pretty thoroughly with all the C compiler
and Linker switches. 

I have about 37 C files with tons of functions that I try to link with 
the given libraries. 
Under Unix the executable is about 256K.  I have rearragned
the link command several ways (moved filenames around and different switches)
and get different errors, but bacically all
telling me some offset is out of range.

These are the three errors:
Error 50,  Jump table offset is out of range
Error 48,  PC-relative edit, offset out of range
Error 49,  Computed Reference offset out of range

Now, I suspect that this may have to do with the Libraries since most of the
errors end up comming from or around there.  
I've used the -ss and -srt options.  Again, I get 
different combinations of the above errors.  Could it be that the 
Clibraries are not compiled with the -m -n options allowing 32-bit addressing,
or is totally me!?!

All I want to do is to compile and run my C code.
I have a 68030 processor with 8 meg of memory, 
	just like my SUN workstation, however ....
It is the Mac operating system, trying to be backward compatiable with 
all those little macs?
Should I:
	a. write smaller programs
	b. become a tricky Mac system hack to do relatively straight forward
		simple no nonsense, no tricks programming
	c. get a *real* operating system for this machine, like Mach,
		 or (Oh god!) AUX.
	d. Give up.

Please excuse my scarcasism, but I beleive I am looking at a very powerful
mainframe-like piece of hardware, and it seems to behave like a PDP-8 or
worse. I'm very frustrated.  Can anyone out there lend some insight to
my problem.

Thanks a bunch,
