Using dynamically linked ftns

[Steven N Harp]

I want to add the ginput ftn to my octave code. I have obtained the
code and the patch to the mkoctfile but I am not clear on how to use
the mkoctfile. I looked through the faq and documents but did not see
instructions/details on how to use the mkoctfile and how to link it
in. Should the file ginput.cc be placed in the src directory and the
run config, make and install? 

Thanks

Steve
