+
+_BSD_SOURCE was deprecated, hence switch to use _DEFAULT_SOURCE as well
+to avoid the build from breaking on newer toolchains.

+	  dt is a generic data test program used to verify proper
+	  operation of peripherals, file systems, device drivers,
+	  or any data stream supported by the operating system.
+	  In its' simplest mode of operation, dt writes and then
+	  verifys its' default data pattern, then displays
+	  performance statisics and other test parameters
+	  before exiting. Since verification of data is performed,
+	  dt can be thought of as a generic diagnostic tool.
