6.29 Attributes Syntax
"An attribute specifier list may appear as part of a struct, union or
enum specifier. It may go either immediately after the struct, union
or enum keyword, or after the closing brace. The former syntax is
preferred. Where attribute specifiers follow the closing brace, they
are considered to relate to the structure, union or enumerated type
defined, not to any enclosing declaration the type specifier appears
in, and the type defined is not complete until after the attribute
specifiers."
So use POST_PACK immediately after struct keyword
