Subject: sha256: Make our u32 and u8 fields the same size
X-Git-Url: http://git.ozlabs.org/?p=ccan;a=commitdiff_plain;h=60b3090a54a7c55e7425c8523dab05b790dd664d;hp=cedcaa1bbb44cad610973c449340c0fde9ae0280

sha256: Make our u32 and u8 fields the same size

These are just aliases to a buffer: its customary for these to
have the same size, and makes sizeof() consistent in case anyone
decides to use the members instead of the containing union.
