Eixa kanei akrivos to idio otan eixa akoma suse 6.4.  Gia na deis se
poia paketa einai xorismenos o compiler sou kane:

rpm -qa | grep 2.95.3

Afta mporeis na ta vgaleis me 'rpm -e' otan kaneis install ti dikia
sou version (ektos fisika apo tis shared libs tis c++, kane rpm -ql
gcc gia perissotera).  Kalou kakou krata ta original rpms kapou
proxeira se periptosi pou kati paei strava.

Ego ton gcc-2.95.3 mou ton exo kanei compile me tis parakato entoles:

# build gcc outside the source tree

cd ../
rm -rf build-i686-pc-linux-gnu
mkdir -p build-i686-pc-linux-gnu
cd build-i686-pc-linux-gnu

../gcc-2.95.3/configure \
  --with-gnu-ld \
  --enable-languages=c,c++,f77 \
  --with-system-zlib \
  --prefix=/usr \
  --with-gxx-include-dir=/usr/include/g++ \
  --enable-threads=posix \
  --enable-shared \
  --with-gnu-as \
  --infodir=/usr/share/info \
  --mandir=/usr/share/man \
  --disable-debug

make bootstrap 

Prosoxi! Me ta parapano, dinontas 'make install' tha steileis ton diko
sou gcc kato apo to /usr, to opoio einai ligo risko.  Mia pio asfalis
idea einai na min doseis --prefix kai na paei kato apo /usr/local;
prosopika den eixa pote provlima, alla leme tora.  Dio pragmata akoma:

1) Me gcc 3.0x exo doulepsei poli ligo kai oxi sto diko mou mixanima,
   opote mporei na eimai lathos, alla prospathise na valeis gcc 3.1

2) Min fovasai mipos xalaseis kati.  An exeis proxeira ta original
   rpms tis dianomis sou kai mia bootdisk me ena static /bin/rpm
   mporeis na diorthoseis ta panta poli efkola.
