Where is this set to its default?

[Sam Clegg, 2012/09/17 19:58:16]

IIUC, the visual studio property files define this
property along with its default value (like for all
the other properties in this file).

     {
       get
       {
         AssertNaCl();
-        return GetProperty("ConfigurationGeneral", "NaClIrtPath");
+        return GetProperty("ConfigurationGeneral", "TargetArchitecture");
       }
 
       protected set
       {
       }
     }
 
     /// <summary>
