The effect of the ${../if/packed:/name} macro is not propagated into any
structure, union or C++ class which is member of the structure, union or
C++ class declaration to which the macro is attached.

text: |
When the code is compiled with the GNU C compiler,
and the ${../if/packed:/name} macro is attached to a
struct, union, or C++ class type definition,
and the ``aligned`` attribute or ${../if/aligned:/name} macro
is not used on the struct, union, or C++ class type definition or
any member thereof,
the ${../if/packed:/name} macro shall cause all structure, union, or class
members to be aligned at one bit for a bit-field member and
one byte otherwise.
