Same here. Those warnings also slow down the configure step a lot! emerge --info Portage 2.2_rc23 (default/linux/amd64/2008.0/desktop, gcc-4.1.2, glibc-2.9_p20081201-r2, 2.6.29-rc5-wl x86_64) ================================================================= System uname: Linux-2.6.29-rc5-wl-x86_64-Intel-R-_Core-TM-2_CPU_T7600_@_2.33GHz-with-glibc2.2.5 Timestamp of tree: Sun, 01 Mar 2009 10:45:01 +0000 distcc 3.1 x86_64-pc-linux-gnu [disabled] ccache version 2.4 [disabled] app-shells/bash: 3.2_p48-r1 dev-java/java-config: 2.1.7 dev-lang/python: 2.5.4-r2 dev-util/ccache: 2.4-r8 dev-util/cmake: 2.6.2-r1 sys-apps/baselayout: 2.0.0 sys-apps/openrc: 0.4.3-r1 sys-apps/sandbox: 1.3.8 sys-devel/autoconf: 2.13, 2.63 sys-devel/automake: 1.5, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10.2 sys-devel/binutils: 2.19.1 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.6a virtual/os-headers: 2.6.28-r1 ACCEPT_KEYWORDS="amd64 ~amd64" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -march=nocona -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/config" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo /etc/texmf/language.dat.d /etc/texmf/language.def.d /etc/texmf/updmap.d /etc/texmf/web2c /etc/udev/rules.d" CXXFLAGS="-O2 -march=nocona -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="distlocks fixpackages parallel-fetch preserve-libs protect-owned sandbox sfperms strict unmerge-orphans userfetch userpriv usersandbox" GENTOO_MIRRORS="http://mirror.switch.ch/ftp/mirror/gentoo/ ftp://ftp.unina.it/pub/linux/distributions/gentoo/" LANG="it_IT.UTF-8" LC_ALL="it_IT.UTF-8" LDFLAGS="-Wl,-O1" LINGUAS="it" MAKEOPTS="-j3" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_EXTRA_OPTS="--human-readable --prune-empty-dirs" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/portage/local/pesa" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="X a52 aac acl acpi alsa amd64 audiofile avahi bash-completion berkdb bluetooth branding bzip2 cairo caps cddb cdr cli cracklib crypt curl curlwrappers dbus djvu dri dts dv dvd dvdr dvdread emacs emboss encode evo exif expat fam ffmpeg fftw flac fontconfig ftp gd gdbm gif glut gmp gnutls gpm graphviz hal iconv idn ieee1394 imagemagick imlib ipod ipv6 isdnlog jabber java5 java6 javascript jpeg jpeg2k kde kdehiddenvisibility lame latex lcms ldap libsamplerate lirc lm_sensors lua lzo mad matroska midi mmap mmx mng mozilla mp3 mpeg mplayer msn mudflap multilib musepack musicbrainz ncurses nls nptl nptlonly nsplugin offensive ogg opengl openmp pam pch pcre pdf png ppds pppd pulseaudio python qt3 qt3support qt4 quicktime readline reflection ruby samba sasl sdl session slang sndfile snmp socks5 speex spell spl sqlite sqlite3 sse sse2 ssl startup-notification svg sysfs taglib tcpd theora threads tiff truetype unicode usb v4l2 vcd vorbis wifi wmf x264 xcb xcomposite xine xinerama xml xorg xpm xulrunner xv xvid zlib" ALSA_CARDS="hda-intel" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" ELIBC="glibc" INPUT_DEVICES="evdev synaptics" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="it" LIRC_DEVICES="inputlirc sir" USERLAND="GNU" VIDEO_CARDS="radeonhd vesa" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, INSTALL_MASK, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS
