Hi, Bill. Thanks for the tips on the compilation control flags, I'll give them a go, and see what happens. I usually stick with whatever default optimisations a "./configure" run would utilise, so I'm unaware of anything that could adversely affect compilation.
As for the source code itself, my C knowledge isn't all that great, so I have no idea about where I should begin, as far as fixing the defective code goes. Tyson.
