--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
What glibc you are using?
libstdc++ refers to __libc_single_threaded only with
#elif __has_include(<sys/single_threaded.h>)
return ::__libc_single_threaded;
#else
and the sys/single_threaded.h header has been added in Glibc 2.32 together with
the __libc_single_threaded symbol.
So, are you doing a native build or cross-compilation (without sysroot?)?
Do you have some unrelated sys/single_threaded.h header around, or are
compiling against glibc 2.32+ headers and linking against glibc 2.31 or
earlier?
