Structure Assignment?

[gillies at p.cs.uiuc.edu]

Recently, there was some discussion about a Lightspeed C function
which returned a structure.  Are the following structure features
in draft ANSII C?

	structure return from a function
	structure passing to a function
	structure assignment among variables

Lightspeed C claims to be "ANSII compatible", but gags on the
structure assignment, after a function returns the value.  The book,
"C: A Reference Manual" just says, "newer compilers now allow
structures to be assigned, ...."  This is vague.
