I have tested this new GCC version as promised, in the temporary phase, both stage 1 and stage 2, everything correct without any kind of problems, in the chroot phase exactly the same results, perfect compilation, here's the output of the final toolchain test as a successful proof of the exercise:

root:/sources/gcc-build# echo 'main(){}' > dummy.c
root:/sources/gcc-build# cc dummy.c -v -Wl,--verbose &> dummy.log

I have not continued the rest of the package tests as it wasn't my purpose, just to test the compiler, although I continued compiling until coreutils just to have some packages compiled with the new toolchain and all went successful, hence I recommend upgrading GCC version for the book, but, every comment and review would be greatly appreciated so we all can be sure

Ok, I resolved my problem with shadow, so I was able to complete the system build up to the final chapter, and a little beautification with the configuration scripts in the first chapter of BLFS, all packages compiled with this new version of the GCC 4.2.x series, and all of them ran successfully without any kind of error.

As I'm still studying the diff and patch programs (all those line & number formatting options still drive me a bit crazy), I'm not in a position to produce a patch for the book, and as this package is one of the most critical one (as being part of the toolchain), for this time I would like someone giving it a review, just to be sure everything works ok, from my part, it does ;)

Updates GCC version to 4.2.4.

Tickets should not be closed as fixed until the changes are incorporated in the book.

Duplicate of #2177 which has already been closed.
