I used the default sources set by cross-hurd in vars.sh:

It doesn't seem to work. Which directory do I include? /usr/include? ./glibc/libpthread/sysdeps/pthread/bits? ./glibc/libpthread/sysdeps/generic/? You're referring to CFLAGS="-I/directory" ./configure, correct?

using the hurd libpthread repo and adding it as an add-on.
libpthread appears to be in the glibc directory, and is getting passed to configure.
