Hi Tobin,
nice to know that you also thinking about this fixes. I think that is
just a first step because I noticed much more warning with
big/little-endian issues and perhaps no one else want to touch this.
I'm also here to help if it is something will be incorrect ;)."
Sorry for my previous messages. Sometimes I forget about crtl+s will
sending my e-mails, so if you received other messages just ignore it.
