When I tried to emerge glibc on my new gcc 3.4 laptop I got the message that 'the compiler must support C cleanup handling'. I did some research and found out that 1. I am the only person with this problem (who complained about it) 2. This configure error isn't there when I use -nptl in my use flags 3. It is fixed when I remove the CFLAG -fprefetch-loop-arrays Reproducible: Always Steps to Reproduce: 1. add nptl to you use flags 2. add -fprefetch-loop-arrays to your CFLAGS 3. emerge glibc Actual Results: ./configure stops with the message: the compiler must support C cleanup handling Expected Results: glibc to move on to '* Building GLIBC..." laptop ~ # emerge info Portage 2.0.51_rc1 (gcc34-x86-2004.2, gcc-3.4.2, glibc-2.3.4.20040808-r0, 2.6.9-rc1 i686) ================================================================= System uname: 2.6.9-rc1 i686 Intel(R) Pentium(R) M processor 1.70GHz Gentoo Base System version 1.5.3 ccache version 2.3 [enabled] Autoconf: sys-devel/autoconf-2.59-r4 Automake: sys-devel/automake-1.8.5-r1 Binutils: sys-devel/binutils-2.15.90.0.1.1-r3 Headers: sys-kernel/linux26-headers-2.6.8.1 Libtools: sys-devel/libtool-1.5.2-r5 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CFLAGS="-O3 -march=pentium-m -fomit-frame-pointer -fforce-addr -fprefetch-loop-arrays -falign-functions=64 -ftracer -mfpmath=sse" CHOST="i686-pc-linux-gnu" COMPILER="" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3/share/config /usr/share/config /usr/share/texmf/dvipdfm/config/ /usr/share/texmf/dvips/config/ /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/config/ /usr/share/texmf/xdvi/ /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O3 -march=pentium-m -fomit-frame-pointer -fforce-addr -fprefetch-loop-arrays -falign-functions=64 -ftracer -mfpmath=sse" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs ccache sandbox" GENTOO_MIRRORS="http://gentoo.osuosl.org http://distro.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 X aalib acpi alsa audiofile avi bzlib cdr crypt dga directfbx divx4linux dvd encode extensions faac faad fbcon flac freetype ftp gcj gd gif gtk gtk2 imagemagick imlib ipv6 java javascript jp2 jpeg lcms libcaca live lzw mad mikmod mmx motif mpeg msn ncurses nptl oggvorbis opengl pam pcmcia pdflib perl pic png pnp python qt quicktime radeon readline sdl sockets spell sse ssl stroke svga tcltk tcpd tetex tiff truetype trusted usb wmf wxwindows xml xml2 xmms xosd xv xvid zlib video_cards_radeon"

-fprefetch-loop-arrays is filtered out of CFLAGS, so this bug probably should've been closed a while ago...

*** Bug 101310 has been marked as a duplicate of this bug. ***
Seems like it's not fixed, glibc-2.3.5-r1 fails as well.
Due to how flag-o-matic is, -fprefetch-loop-arrays is kept in CFLAGS if you are running ~arch, since its declared to be an "unstable flag". We either need to rip it out of there, or strip it in the glibc builds.
fixed
