Takatoshi Kondo	a0e4294b5a	Set MSGPACK_ZONE_ALIGNOF(char) explicitly. It makes efficient zone allocation. If it was omitted, the default alignment was applied. It was inefficient.	2017-07-23 19:11:12 +09:00

Takatoshi Kondo	10be66712d	Partially fixed #460 . If msgpack-c compiles on "sparc" platform, then define MSGPACK_ZONE_ALIGN=8 macro. It allocates 8byte (64bit) alignment memory on zone allocating.	2017-07-20 11:00:16 +09:00
