It looks like you are building the code meant for POSIX platforms on a
native Windows system, and that system's POSIX threads emulation is deficient.

Try configuring with --enable-threads=windows, as documented in
https://www.gnu.org/software/gnulib/manual/html_node/Gnulib-multithreading.html

If that works fine and you want to make it the default, add an invocation of
gl_AVOID_WINPTHREAD to your configure.ac file.
