+#
+# 2. compile and link a test dll with ".sl" (i.e. != ".dll") extension.
+#
+# 3. compile and link a client application linking directly to the ".dll" dll built in 1.
+# This should produce no errors.
+#
+# 4. compile and link a client application linking directly to the ".sl" dll built in 2.
+# This should produce no errors.
+#
+# 5. compile and link a client application linking directly to a symlink into

+# This should produce no errors.

+# 6. compile and link a client application linking directly to a symlink into
