I can confirm GCC 13.2.0 builds with MinGW-w64 11.0.1 without explicitly
configuring with LDFLAGS="-pthread"

Is there still such an error for you?

It looks to me that this linker command line did not contain `-pthread` unlike
the ones above. Maybe the configure script is worth looking at.

```

Just to clarify: libwinpthread is built as part of the GCC build against
MinGW-w64.
MinGW-w64 also already has a libwinpthread (including libwinpthread-1.dll which
can be found in the PATH).

By the time I get to that error the build process already generated these
files:
- mingw-w64/mingw/lib/libwinpthread.a
- mingw-w64/mingw/lib/libwinpthread.dll.a
- mingw-w64/mingw/lib/libwinpthread.la
However I couldn't find a matching DLL, which I assume should be here:
- mingw-w64/mingw/bin/libwinpthread-1.dll

I Noticed:
--enable-threads=posix 
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):

More undefined references to pthread_*

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