Comment (by evanmiller):

 Interestingly, just the regular pack directives work as expected with gcc-
 apple-4.2:

 {{{
 #include <stdint.h>

 #pragma pack(push, 1)
 typedef struct
 {
   uint32_t id;
   uint16_t pos;
 } DzlFuzzyMutableIndexItem;
 #pragma pack(pop)

 int main() {
     return sizeof(DzlFuzzyMutableIndexItem);
 }
 }}}

 {{{
 $ gcc-mp-7 test-pack.c && ./a.out
 $ echo $?
 8

 $ gcc-apple-4.2 test-pack.c && ./a.out
 $ echo $?
 6
 }}}

 So the struct-padding algorithm changed at some point.
