All right.

I have just installed 0104 version in the 486 mandrake 6.1 and it
works(I goes very smooth with fft2 disabled, but when I set ftt2 on 
svgalib gets a "segmentation fault reveived") but I CAN NOT compile it in
the Mandrake 9.1 with the athlon.

I get the following error at the beginning of the compiling session,
when compiling uivar.c file:

I like this new version, I like the new waterfall and the parameters
config included in the graph, saving space on the screen.
I'll tell you more new as I play enough with all versions.
