Hi John,

I wonder if the above error might be related to the other .so.6 C++
problem?

What does:

cat << EOF > t.c
main () {}
EOF

/home/build/opt/gcc/bld/gm2/./prev-gcc/xgcc \
 -B/home/build/opt/gcc/bld/gm2/./prev-gcc/  \
 -B/home/build/gm2/2022-02-11/sparc64-unknown-netbsd9.1/bin/ \

 /home/build/gm2/2022-02-11/sparc64-unknown-netbsd9.1/sys-include \
 -fno-checking t.c

generate?
