 2 * Declare directives for structure packing. No padding will be provided
 3 * between the members of packed structures, and therefore, there is no
 4 * guarantee that structure members will be aligned.
 5 *
 6 * Declaring packed structures is compiler specific. In order to handle all
 7 * cases, packed structures should be delared as:
 8 *
 9 * #include <packed_section_start.h>
10 *
11 * typedef BWL_PRE_PACKED_STRUCT struct foobar_t {
12 *    some_struct_members;
13 * } BWL_POST_PACKED_STRUCT foobar_t;
14 *
15 * #include <packed_section_end.h>
