I don’t think so.  Given that libpthread is a libc add-on, its headers
should be picked automatically.  We should check with bug-hurd people,
and keep what you’ve done in the meantime.

It’s very surprising that the manual doesn’t build, not even with
Texinfo 4.

Regarding nscd, the build log you posted shows that the problem is a
conflict between Mach’s thread_info type and nscd’s.  I’ve just emailed
bug-hurd.

The patch itself looks good to me!  Some mostly cosmetic comments:

Please call the latter glibc-hurd-extern-inline.patch, for instance.

+This will allow libpthread to be build as an addon.

Likewise, please add a sentence explaining what’s going on, possibly
with links to discussions on the subject.

+There is no definition for  __thread_terminate_release yet, so according to 
Samuel we disable it.

Same, better explain why __thread_terminate_release is missing, why it’s
OK to remove that call, with a link to the discussion.

+__SPIN_LOCK_INITIALIZER gets defined to zero so we can start using libpthread.

Same here.

These are all small changes, but I think it’s important to keep track of
why all these things are done this way, because it’s not trivial.

Thank you!
