sys-devel/gcc-8.2.0-r2::gentoo was built with the following:
USE="cxx fortran graphite (multilib) nls nptl openmp pch (pie) sanitize ssp vtv (-altivec) -debug -doc (-fixed-point) -go (-hardened) (-jit) (-libssp) -mpx -objc -objc++ -objc-gc -pgo -regression-test -systemtap -vanilla" ABI_X86="(64)"
CFLAGS="-g -pipe -O2 -Wall -Wformat=2 -march=amdfam10 -mtune=amdfam10 -Wno-comment"
CXXFLAGS="-g -pipe -O2 -Wall -Wformat=2 -march=amdfam10 -mtune=amdfam10"
I think it's now caused by the fact that we pass CXXFLAGS through after bug #581406 and now checking -Werror abainst user's flags. Let'ss how easy it is to drop -Werror. I saw similar error when cross-building gcc (when host's gcc version was used for most builds). There are 3 unconditional -Werror injections we should remove or put under --disable-werror: $ git grep -B2 -E 'XCFLAGS=.*Werror' | cat libatomic/configure-# Add -Wall -Werror if we are using GCC. libatomic/configure-if test "x$GCC" = "xyes"; then libatomic/configure: XCFLAGS="$XCFLAGS -Wall -Werror" -- libatomic/configure.ac-# Add -Wall -Werror if we are using GCC. libatomic/configure.ac-if test "x$GCC" = "xyes"; then libatomic/configure.ac: XCFLAGS="$XCFLAGS -Wall -Werror" -- libgomp/configure-# Add -Wall -Werror if we are using GCC. libgomp/configure-if test "x$GCC" = "xyes"; then libgomp/configure: XCFLAGS="$XCFLAGS -Wall -Werror" -- libgomp/configure.ac-# Add -Wall -Werror if we are using GCC. libgomp/configure.ac-if test "x$GCC" = "xyes"; then libgomp/configure.ac: XCFLAGS="$XCFLAGS -Wall -Werror" -- libitm/configure-# Add -Wall -Werror if we are using GCC. libitm/configure-if test "x$GCC" = "xyes"; then libitm/configure: XCFLAGS="$XCFLAGS -Wall -Werror" -- libitm/configure.ac-# Add -Wall -Werror if we are using GCC. libitm/configure.ac-if test "x$GCC" = "xyes"; then libitm/configure.ac: XCFLAGS="$XCFLAGS -Wall -Werror" Created attachment 548010 [details, diff]

Please check if gcc-8.2.0-no-werror.patch works for you.
I'll also check it locally and apply on affected gcc versions.
