--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I Noticed:
--enable-threads=3Dposix=20
and the error message is:

D:\prog\winlibs32_stage\mingw32\i686-w64-mingw32\bin\ld.exe:
R:/winlibs32_stage/gcc-11-20210404/build_mingw/gcc/libgcc_eh.a(unwind-dw2.o=
):
in function `_gthread_once':
R:\winlibs32_stage\gcc-11-20210404\build_mingw\i686-w64-mingw32\libgcc/./gt=
hr-default.h:700:
undefined reference to `pthread_once'
....
More undefined references to pthread_*

Either pthreads-win32 is not installed correctly or is not being linked
correctly here.=
