That should probably be __main=__tinymain (two underscores instead of
one.  You're replacing the routine _main, and Lattice prepends an
underscore to every routine name, hence __main).  The names may also be 
different if you are using registerized parameters, since Lattice 
prepends an @ instead of an _ when you use them.  If you use one
underscore, I expect that blink would complain about no module
_tinymain and multiple definitions of _main.

If you do this, you do lose several features of the startup code.  No
control-c handler is established for you, and the standard i/o files
(stdin, stdout, stderr) are *not* opened.  You have to open these
yourself (or use lower level/AmigaDOS io calls) if you want to read
or write something to the console window, even if you're running under
a CLI.

This is good advice--look at umain.c and see what it does.

Gee, I don't even have 5.04 yet.  Sounds like it's time to check my
mailbox.
