Comment(by gespinasse):

 Another issue with zlib as this match the subject:[[BR]]

 zlib.h is changed by gentoo, fedora-devel and Arch linux to fix one issue.
 See

 http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-
 libs/zlib/files/zlib-1.2.5-lfs-decls.patch?view=log

 Same effect of gentoo patch could be obtained with a

 sed -i 's|ifdef _LARGEFILE64_SOURCE|ifndef _LARGEFILE64_SOURCE|' zlib.h

 Not sure this is the /right thing/ But at least, this is reported to fix
 compilation failure with pdfedit, cgit, freecad, fatrat, libxlm2, luatex
 (probably only failure on 64-bits compilation, I have only warnings on
 32-bits distrib with libxml2)

 With that change, it remove for me on 32-bits compilation those warning
 when compiling libxml2

 {{{
 xmlIO.c:1175: warning: implicit declaration of function 'gzopen64'
 xmlIO.c:1175: warning: nested extern declaration of 'gzopen64'
 }}}
