go: cmd/cgo: -godefs doesn't handle embedded struct fields correctly

by Mortdeus@gocos2d.org:

Before filing a bug, please check whether it has been fixed since the
latest release. Search the issue tracker and check that you're running the
latest version of Go:

Run "go version" and compare against
http://golang.org/doc/devel/release.html  If a newer version of Go exists,
install it and retry what you did to reproduce the problem.

Thanks.

What steps will reproduce the problem?
This struct...

//<libdrm/drm.h>
struct drm_stats {
        unsigned long count;
    struct {
        unsigned long value;
        enum drm_stat_type type;
    } data[15];
};

When wrapped with cgo as

`
Stats C.struct_drm_stats
`

gets converted by godefs to

`
type Stats struct {
    Count uint64
    Data  [15]_Ctype_struct___0
}
`

What is the expected output?
type Stats struct {
         Count uint64
         Data [15]struct{
              Value uint64 //or uint32
              Type uint32
         }
}

Which compiler are you using (5g, 6g, 8g, gccgo)?
6g

Which operating system are you using?
archlinux x86-64

Which version are you using?  (run 'go version')
go version devel +4a712e80e9b1 Tue Apr 09 15:00:21 2013 -0700 linux/amd64
