Hi,
Now that most of my programs -including octave-2.1.39- are working again
and the aliases and keybinding to which I am used are back in place, I
can try and follow your advice. I did some RTFM, and asked some of my
friends how to do it. I shall sum up the steps I understood I have to
take. Would you please check it and mail me your blessing or
corrections?. As you did it pretty recently, you are likely to remember
correctly all the little details, not only the principles.
1-Download and install somewhere gcc-3.2.2:
	Did that and installed it in /usr/local/gcc-3.2.2. I have there
some executables (notably gcc, g++, g77 -also some others whose role is
unknown to me). There are some libraries and some include files as well.
2-Configure and make octave-2.1.44 with options
CC=/usr/local/gcc-3.2.2/bin/gcc, CXX=/usr/local/gcc-3.2.2/bin/g++,
LD_LIBRARRY_PATH=/usr/local/gcc-3.2.2/lib/. Install it
3-Set LD_LIBRARRY_PATH to /usr/local/gcc-3.2.2/lib/ everytime before
starting octave (By the way, do I have to reset it after leaving the
program ?)

	As an exercise to check/improve my knowledge of the linux
operating system this is interesting, no matter how much better version
2.1.44 is than version 2.1.39. Nevertheless, I looked in the ChangeLog
and NEWS files, to find out what the differences maybe, but I failed.
Where should I look for that ?

I send this letter (also) directly to you, only because this is the way
our correspondence started. As I think that your answer to these
questions migh interest others, as well, I CC-ed the message to the
list.
Thanks for past and future help... Avraham
