It sounds like a recipe for disaster. Please reconsider. Even if you go ahead
and try it, I suspect you will eventually realize it would be far easier to
just fix your source code. I'm just trying to save you some time up front.

Well, I'm not sure what you mean by reference documentation. I have attached
the URLs of the FOLDOC entires for big-endian:
http://www.instantweb.com/foldoc/foldoc.cgi?big-endian and little-endian:
http://www.instantweb.com/foldoc/foldoc.cgi?little-endian and NUXI problem:
http://www.instantweb.com/foldoc/foldoc.cgi?NUXI+problem

Note from the above that the SPARC chip is big-endian, and the x86 intel
processors are little-endian. The PowerPC is "bytesexual", but I believe most
OS's make it big-endian.

This is generally only an issue when binary data has to be transferred from
one platform to the other. If you are just converting source code, you
probably won't have a problem.
