Our previous include file only supplied a very limited set of wrapper redefinitions for platforms that define __APPLE__ (i.e. Mac OS). In particular, some needed big endian conversions were missing, causing "symbol(s) not found" errors when linking. Instead of patching the existing file, let's do away with it completely and replace it by something more sophisticated. The portable_endian.h used is in the public domain, and was taken from https://gist.github.com/panzi/6856583 Signed-off-by: Bernhard Nortmann <bernhard.nortmann@web.de>
