It seems you have some additional options set? Well, I've already found that unsetting of CFLAGS in /etc/make.conf fixes building. The values of CFLAGS was: (both 4.10 hosts) CFLAGS= -O -pipe -march=i586 -mcpu=i686 -mpreferred-stack-boundary=2 (4.8 host with the same problem! hence it isn't special for 4.10) CFLAGS= -O2 -pipe -mcpu=i686 -march=i486 -mpreferred-stack-boundary=2 The strangeness is seen in libiberty config log diffs for good variant (without CFLAGS) and bad variant: configure:3410: checking for sys/file.h -configure:3424: /usr/ports/lang/gcc34/work/build/gcc/xgcc -B/usr/ports/lang/gcc 34/work/build/gcc/ -B/usr/local/gcc34-port/i386-portbld-freebsd4.10/bin/ -B/usr/ local/gcc34-port/i386-portbld-freebsd4.10/lib/ -isystem /usr/local/gcc34-port/i3 86-portbld-freebsd4.10/include -isystem /usr/local/gcc34-port/i386-portbld-freeb sd4.10/sys-include -E -O2 conftest.c +configure:3424: /usr/ports/lang/gcc34/work/build/gcc/xgcc -B/usr/ports/lang/gcc 34/work/build/gcc/ -B/usr/local/gcc34-port/i386-portbld-freebsd4.10/bin/ -B/usr/ local/gcc34-port/i386-portbld-freebsd4.10/lib/ -isystem /usr/local/gcc34-port/i3 86-portbld-freebsd4.10/include -isystem /usr/local/gcc34-port/i386-portbld-freeb sd4.10/sys-include -E -O2 -O -pipe -march=i586 -mcpu=i686 -mpreferred-stack-boun dary=2 conftest.c +`-mcpu=' is deprecated.

Difference begins only from testing for <sys/file.h>. And, not all following tests fail. The third attempt was on 4.10 with the following CFLAGS: CFLAGS= -O -pipe -march=i686 It bypassed the problematic place. So, is it -mpreferred-stack-boundary? I'll retest as soon as possible. -netch-
