Thank you very much for your reply.
I tried with success to compile gcc 2.95, but when I try to compile gcc 3.3.4
with gcc 2.95, I see this error:

gcc   -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long   -DHAVE_CONFIG_H
-DGENERATOR_FILE  -o gengenrtl \
 gengenrtl.o ../libiberty/libiberty.a
./gengenrtl -h > tmp-genrtl.h
Segmentation Fault - core dumped
make[1]: *** [s-genrtl] Error 139
make[1]: Leaving directory `/usr1/bruzzonem/obj334/gcc'
make: *** [all-gcc] Error 2


So, could you help me again?

all the best.
