New Revision: 3439

Modified:
trunk/varnish-cache/configure.ac
trunk/varnish-cache/lib/libvarnish/vsha256.c
Log:
Try to get the endianess optimization working, by including an assortment
of possibly relevant headers and only go with the fast path if we have
credible information that this is a big-endian platform.
