+** Guile COOP threads are now compatible with LinuxThreads
+
+Previously, COOP threading wasn't possible in applications linked with
+Linux POSIX threads due to their use of the stack pointer to find the
+thread context.  This has now been fixed with a workaround which uses

+Compose/decompose an SCM value.

+The SCM type is now defined as void * on most architectures.  This
+makes it easier to find several types of bugs, for example when SCM
+values are treated as integers without conversion.  Values of the SCM
+type should be treated as "atomic" values.  These macros are used when
+composing/decomposing an SCM value, either because you want to access
+individual bits, or because you want to treat it as an integer value.

+E.g., in order to set bit 7 in an SCM value x, use the expression
