Well.. Actually I was NOT able to get them right with bzip2recover.

The gcc-4.6.2.tar.bz2 is corrupted as well. (other not-mentioned releases were
ok).

More information:

 * Untar the file:

boris@server:gcc$ wget
http://ftp.gnu.org/gnu/gcc/gcc-4.6.2/gcc-4.6.2.tar.bz2.sig
boris@server:gcc$ tar xjf ../../applis/src/gcc/gcc-4.6.1.tar.bz2

bzip2: Compressed file ends unexpectedly;
        perhaps it is corrupted?  *Possible* reason follows.
bzip2: Inappropriate ioctl for device
        Input file = (stdin), output file = (stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.

I verified the signature of the build..

Could it come from my setup?

Thanks,
