Why is HJLs Binutils not in the book?
The binutils release that you typically find on ftp.gnu.org is commonly known as the “FSF” binutils. Noted hacker H.J. Lu also makes releases out of the main CVS repository and these are commonly known as the “HJL” binutils and can usually be found on ftp.kernel.org. Debate often arises over which version to use due to the fact that most mainstream distros tend to use the HJL releases even though they are typically marked as “beta”.
