New pth attempt - failed (for now)
I was trying to get a pthread substitute going and tried
old pth. Apparently this has been done before and the
same problems - tests for sigstack and sigaltstack make
Hurd go out to lunch.
I think it will compile, and I am hacking configure.in
to try and disable these tests and go with the failsafe
If pth works, and provides pthreads, it might be a
stopgap measure to get some other packages in the
works until such a time as our libc pthreads are done.
