Recently, from 1.16.2 to 1.17.1 include/platform.h changed its endianess
detection and it broke compilation on Mac OS X. It seems this broke OpenBSD as


I would suspect it probably breaks NetBSD also. The patch provided in the
mailing list does not work for Mac OS X. If __APPLE__ is treated like
__FreeBSD__ everything compiles fine. For example,

This worked for me for Mac OS X and OpenBSD.. I'd suspect it fixes NetBSD also,
but its untested.
