 Which versions did you try?

All.

- 3.0.1
- 3.0.2
- 3.0.3
- 3.0.4
- 3.1
- 3.1.1
- 3.2
- 3.2.1

This took me about one year! Because after compile and install
of the compile I rebuilt or at least I tried to rebuild all of

1. binutils
2. gcc again, with the new binutils from step 1
3. linux kernel
4. modutils
5. glibc-2.2.5

After the rebuild of all this I run the new installation and
tested out some applications including

- apache
- mysql
- squid
- ssh
- wu-ftpd
- openssl
- ISC bind
- gdb

The test consisted of compile/build, install and run some test
scripts comparing the results to the correct results generated
on a gcc-2.95.3 based installation.

When ever I found fatal errors I went to the next gcc version
starting at the beginning of the build process but it got worse
from version to version.

At the end I gave up and reinstalled the system totally based on
gcc-2.95.3. - That's the story.
