Would this be a problem: powerpc*) cputype=`((grep cpu /proc/cpuinfo | head -n 1 | cut -d: -f2 | cut -d, -f1 | $SED 's/ //g') ; /usr/bin/machine ; /bin/machine; grep CPU /var/run/dmesg.boot | head -n 1 | cut -d" " -f2) 2> /dev/null` cputype=`echo $cputype | $SED -e 's/ppc//g;s/ *//g'` case $cputype in *750*) ax_gcc_arch="750 G3" ;; *740[[0-9]]*) ax_gcc_arch="$cputype 7400 G4" ;; *74[[4-5]][[0-9]]*) ax_gcc_arch="$cputype 7450 G4" ;; *74[[0-9]][[0-9]]*) ax_gcc_arch="$cputype G4" ;; *970*) ax_gcc_arch="970 G5 power4";; *POWER4*|*power4*|*gq*) ax_gcc_arch="power4 970";; *POWER5*|*power5*|*gr*|*gs*) ax_gcc_arch="power5 power4 970";; 603ev|8240) ax_gcc_arch="$cputype 603e 603";; *POWER7*) ax_gcc_arch="power7";; *POWER8*) ax_gcc_arch="power8";; *POWER9*) ax_gcc_arch="power9";; *POWER10*) ax_gcc_arch="power10";; *) ax_gcc_arch=$cputype ;; esac ax_gcc_arch="$ax_gcc_arch powerpc" ;; I saw that in m4/ax_gcc_archflag.m4 I guess related would be this configure option: --with-gcc-arch=<arch> use architecture <arch> for gcc -march/-mtune, instead of guessing -- Len Sorensen
