An enum tag under C++ is already a typedef so the above is redundancy (both
the original and the CORRECTED version. 
A look at c_varieties.h in at least the SUN version of C++ 2.0 indicates
that specifying enum my_type my_func (... as illegal. They provide a macro
to deal with the differences:
-- start of included segment from comment section of that file --
 * enum type specifier:
 *	In K&R C, it is OK to use "enum xyz" as return type but in C++,
 * 	one should use "xyz".  ENUM_TYPE macro is used to handle this.
 *
 *		ENUM_TYPE(enum, xyz) (*func) (...);

 I hope this helps. And please do not use typedefs to dupplicate one of the
 great features of C++ :-).
