EOF is *not* a char. It is a negative *int* #defined in the header
<stdio.h>. While the implementation will change from implementation
(it is usually defined as -1) the meaning is independent and you don't
need to know the value. EOF will be returned by fgetc and similar
functions to indicate that you tried to read beyond end-of-file.

Not that in order to compare the return value of fgetc etc. to EOF you
have to assign it to an *int*.

	int c;  /* !!! */
	...

	while ((c=fgetc(p)) != EOF) ....
