Hi Paul,

I wouldn't call it "the gnulib i18n code". The modules 'lock', 'tls',
etc. are needed by the modules 'strsignal', 'fstrcmp', and 'localename'.
Basically, every piece of code that wants to provide multithreaded
access to a global variable (may it be a registry or cache or anything)
needs locking.

Sure, when gnulib provides a "replacement" of a system header, it should
not remove features from the system headers that other parties may rely
upon.

It would be wise to include <pthread.h> here. Not all systems define
these types in <sys/types.h>; some (e.g. mingw pthreads-win32) require
a #include <pthread.h>. This include is not part of AC_INCLUDES_DEFAULT.
