Lattice/UNIX incompatibility

[Andrew Koenig]

Every version of the Lattice compiler I have seen has four
non-standard things:

	1. Comments nest.

	2. If you try to pass a structure to a function
	   it quietly passes a pointer to the structure.

	3. Every declaration of an external variable but
	   one must say 'extern'.

	4. Case is ignored in external variables.

This makes it quite a nuisance to port Unix applications.
