* Changes to the distribution
-** There is a new thread implementation option "null", which is also
- the default now.
+** There are two new thread implementation options: "null" and
+ "coop-pthreads".
When you configure "--with-threads=null", you will get the usual
threading API (call-with-new-thread, make-mutex, etc), but you can't
is always present, although you might not be able to create new
threads.
-When cooperative threading is not supported on your platform, you will
-get the "null" threads instead.
+When "coop" threading is not supported on your platform, you will get
+the "null" threads instead.
-The long term plan is to make the selection of a thread implementation
-a run-time option, not a configure time option.
+The "coop-pthread" (or shorter: "copt") thread implementation will use
+portable POSIX threads but will restrict them so that only one thread
+can execute 'in Guile' at any one time. This option will give you the
+same basic behavior as the "coop" option, but hopefully in a more
+portable way.
** Guile now includes its own version of libltdl.

+
+ * coop-pthreads.c, coop-pthreads.h: Redone completely, you might
+ start testing it now.
+
+ * _scm.h: Include <errno.h< so that SCM_SYSCALL is correctly
+ defined when HAVE_RESTARTABLE_SYSCALLS is not defined.
+ (HAVE_RESTARTABLE_SYSCALLS): Do not define when USE_COPT_THREADS
+ is defined.
