I tried both of these addresses and they bombed, such are the vagaries of

Comments on the Lattice C compiler version 3.10

>   a. comparative efficiency of object code produced ( time and space )

Lattice has made great gains in this area, I would speculate that this
is due to pressure put on them by Manx. Load modules that don't use 
printf are comparable now.

Lattice is going straight for the ANSI standard. This is probably a good
thing, they don't seem to know which way to jump with the library yet
but this version has lots of neat new functions, including support for
the FFP routines and some new ieee routines.

I just found one in the *library* that causes file pointers to switch
back from unbuffered to buffered. Luckily this version of the compiler
comes with an Object Module Librarian so putting in the fix is easy.

Since Lattice comes with the developers package this is not unusual, it
is also easier to port your programs back to to a PC this way (should you
ever want to) Generally most stuff will compile on either compiler again
the biggest problem is the libraries and the fact that the Amiga system
calls really want 32 bit ints not 16 bit ones.

A matter of personal preference, the cheapest version of Lattice ($225)
now, comes with the text utilities grep, files, splat, wc, etc and an
assembler, and the Blink linker, and the compiler. Combined with microemacs
and the Software Distilleries make program you have a pretty complete
development environment. 

In general for serious Assembly work you will probably want the MetaCompCo
assembler (Scotts Valley, CA) or the DevPAC from the guys in britain.

[These are definitely my own opinions here!]
