 I placed both 32-bit UID/GID versions ahead of their respective 16-bit 
counterparts, recognising that the 32-bit versions are the default in BFD, 
which in turns follows Linux's <asm-generic/posix_types.h> default.  The 
32-bit UID/GID versions are also the predominant choice in Linux, for both 
32-bit ports (ARC, Blackfin, TI C6X, H8/300, Hexagon*, Meta, MicroBlaze, 
MIPS, Nios II, OpenRISC, PA-RISC, PowerPC, TILE, UniCore-32*, Xtensa) and 
64-bit ports (all except SuperH).

 I hope it clarifies my choice and I think it makes sense this way.
