The attached patch fixes this, at least if the first element of the
union is not a bitfield.
Bitfields can really not be represented properly in Go (think about
constructs like "struct { int : 1; int bf : 1; }"), I'd rather not
try to represent them in a predictable way. The patched code may
or may not give them a name, and reserves the proper amount of
padding where required in structs. If a union begins with an
anonymous bitfield (which makes no sense), that is ignored. If a
union begins with a named bitfield (possibly after unnamed ones),
this may or may not be used as the (sole) element of the Go
struct.

Subject: [PATCH 1/2] godump: "Fix" handling of anonymous structs and unions.
Remove the "struct { ... }" around them as was the case before.
Note that bitfields are note handled in any predictable way. They may be
replaced by padding or not, and a union beginning with a bitfield may use the
bitfield in the Go struct or may use the first non-bitfield element of the
union. This is not really fixable.
