commit 2ab109b7729774cdfb791c80e855dea61c7b4d2f
Author: Simon McVittie <smcv at debian.org>
Date:   Thu Sep 29 23:37:15 2016 +0100

    Avoid 'register' declarations
    
    gcc 6 with -Wall -Wextra warns:
    
    code/botlib/l_precomp.c: In function ‘PC_NameHash’:
    code/botlib/l_precomp.c:551:2: warning: ‘register’ is not at beginning of declaration [-Wold-style-declaration]
      int register hash, i;
      ^~~
    
    Modern compilers either ignore the register storage class when
    generating code, or generate better code without it, so just remove
    most of them.
    
    The remaining uses are in third-party bundled libraries (libjpeg, zlib),
    and in a PowerPC-specific inline function consisting of inline
    assembler (because I'm not 100% confident that it doesn't have
    some practical use there).
