Case-sensitivity patches now in CVS



Just in case nobody else has built maxima under XP,  I did and I have
not found any problems.   (I used gcl 2.6.5.)

For my own orthopoly code (not in the distribution), I see that I need to
change the cases of the way some functions _display_. 

It's a great joy to type cos(x) and see cos(x) displayed. I thank 
all that contributed.
