Indeed, it is a problem with gcc-2.95 since with gcc-3.1.0 I don't have
illegal instruction. I'll switch to gcc-3.1 and will not continue to use the
old one.
But now, with lyx-1.3 and gcc-3.1, the mouse wheel doesn't want to work
anymore. I'm compiling lyx-1.2 to see if it is related to lyx or system.
