This patch addresses a build failure in OS X. Running git-bisect on a straightforward build (bootstrap, autogen.sh, configure, make, make install) showed this as the "Bad commit:" 3e7c039799cddc45517350cc917eb10715f33fec The issue is that hivex-internal.h uses le32toh in a static inline function. In case `configure` doesn't find le32toh, byte_conversions.h defines it. But hivex-internal.h doesn't include the safety definition. OS X demonstrates this a problem. Neither endian.h nor byteswap.h are found with `configure` in OS X 10.8.5 (XCode 5), but the headers are both found in Fedora 19 and Ubuntu 13.04. This patch to configure.ac further logs that only ntohl is available for byte swaps: @@ -153,6 +153,8 @@ AC_REPLACE_FUNCS([mmap]) dnl Functions.

(As another aside, this is an interesting example of lazy symbol binding failing with an inline function.) The problem is resolved by having hivex-internal.h include byte_conversions.h. This obviates most of the other direct inclusions of byte_conversions.h. (One persists under sh/.) This patch builds and runs hivexml on images/large fine in Ubuntu 13.04 and Fedora 19. It also allows builds to succeed in OS X, but doesn't run hivexml for an unrelated reason. The _iconv_open symbol-not-found issue, that I thought was previously resolved (491ba0f7a761c7ffd50e0eaa4d892f78d538eb2b), resurfaced.
