The ANSI X3J11 committee is still very active, but they haven't
finished yet.  The latest draft standard that I have a copy of
is Doc. No. X3J11/85-138 (Nov. 11, 1985); it should be available
through the X3 Secretariat: CBEMA, 311 First St NW, Washington
DC 20001 (202)737-8888.

I don't think there is a separate IEEE C effort at present.
There is a Portable Operating System Environment standards
working group (P1003) that has just ballotted on a proposed
trial use (UNIX system interface) standard.

How about the C Reference Manual in the UNIX System V docs?

"Two types are the same if they have the same ordered set of
type specifiers and abstract declarators, either directly or
via typedefs.  Two structures or unions are different if they
have no names or different names (taking tags and typedef
synonyms into account), even if their members are identical."

(void *) is a type capable of being assigned a pointer to
anything and back without loss of information.

Simple assignment requires both operands to be arithmetic
types or to have the same structure, union, or pointer type.

Only if you want parameter type checking and coercion.

Since the standard has not yet been ratified, a book would
be premature.
