To quote K&R section 6.2:
"There are a number of restrictions on C structures.  The essential rules
are that the only operations that you can perform on a structure are take
its address with &, and accesss one of its members.  This implies that
structures may not be assigned or copied as a unit, and that they can not be
passed to or returned from functions.  (These restrictions will be removed
in forthcoming versions.)"

As I recall a number of 'C' compilers considered a structure to be more like
an array than like a single variable, so structures were implicitly passed
by reference (in the same manner as arrays still are).

BTW:  I vote for the Import(Ansi_C,...)  which should solve the problem more
easily in new code.
