+ * GNU diff, for `make check' to complete properly. (We intend to

+A few system-specific issues have been noted. These may be PSPP bugs
+or system bugs; we have not yet been able to track them down precisely:
+
+ * On Solaris, one or more tests may fail `make check'. We have
+ only seen this reported on Solaris 9 with GCC 3.4.2. Our
+ reporter says that turning off optimization (with -O0) at least
+ masked the symptoms.
+
+ * On Mac OS X, GCC 4.0.0 build 4061 has been observed to cause
+ some tests to fail. Later builds should work fine.
