+=== UNIXGCC Debug ===\r
+\r
+If you build with the UNIXGCC toolchain, then debugging will be disabled\r
+due to larger image sizes being produced by the UNIXGCC toolchain. The\r
+first choice recommendation is to use GCC44 or newer instead.\r
+\r
+If you must use UNIXGCC, then you can override the build options for\r
+particular libraries and modules in the .dsc to re-enable debugging\r
+selectively. For example:\r
