+Subject: [PATCH] unit-tests/logging.logger: Fix tests with Guile 2
+
+When tests are run with Guile 2 "logging.logger.scm" would always fail
+due to undefined reference to "mkstemp" that was introduced only in
+Guile 3.  In Guile 2 the procedure is called "mkstemp!".  Also
+"call-with-port" procedure is available only from (rnrs io ports) in
+Guile 2, while in Guile 3 this procedure is available out of box.
+This patch fixes these issues by adding an additional runtime check.
+
+* unit-tests/logging.logger.scm (call-with-temporary-file): Bugfix:
+  Check Guile major version and use "mkstemp!" when Guile 2 is used;
+  use "mkstemp" otherwise.  Also for Guile 2 load "call-with-port"
+  from (rnrs io ports).
