  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.
