K&R, 2nd edition states the following in section A8.7 (bottom of page 219):

   The initializer for a union is either a single expression of the same
   type, or a brace-enclosed initializer for the first member of the union.

Note that MyStruct has one member of type MyUnion.  Since type MyUnion is a
union, it must either be initialize by an expression of type MyUnion or an
brace_enclosed initializer for the first member of the union which has type
char*.  I assume you wish to initialize abc.name to 0.  To do this, you must
have two set of braces:

  MyStruct abc = { {0} }

This compiles without error under gcc 1.36 on a Sun-3M60 running SunOS 4.0.3.
I don't believe the problem you reported is a bug.
