Since version 4.1 the gcc is warning about ignored attributes. This patch is
using the equivalent attribute on the struct instead of on each of the
structure or union members.
GCC Manual:
"Specifying Attributes of Types
packed
This attribute, attached to struct or union type definition, specifies
that
each member of the structure or union is placed to minimize the memory
required. When attached to an enum definition, it indicates that the
smallest integral type should be used.
Specifying this attribute for struct and union types is equivalent to
specifying the packed attribute on each of the structure or union
members."
