BUG: SQLConfigDataSource Returns TRUE Even Without Registry Permissions

Steps to Reproduce Behavior

1. Use Regedit32.exe to disable read and write access to the following key:
   HKEY_CURRENT_USER\Software\ODBC\ODBC.INI
2. Compile and run the following code:

   #include <windows.h>
   #include <sql.h>
   #include <sqlext.h>
   #include <odbcinst.h>
   
   int WINAPI WinMain(HINSTANCE hinst,HINSTANCE pinst,LPSTR szCmd,int nShow)
   {
           // The following code attempts to add a user DSN.
   	if (SQLConfigDataSource(NULL,ODBC_ADD_DSN,
   	 "SQL Server","DSN=YourDSNName\0Server=YourServerName\0\0"))
   	{
   	 MessageBox(NULL,"SQLConfigDataSource succeeded",
   		"SQLConfigDataSource",MB_OK);
   	}
   	else
   	{
   	 MessageBox(NULL,"SQLConfigDataSource failed",
   		"SQLConfigDataSource",MB_OK);
   	}
   	return 0;
   }
   					

   Note that SQLConfigDataSource returns TRUE but the new entry does not exist. If you run this code with the appropriate permissions, the new entry will exist.
