    can also be added into release notes as news features when we release this package.
    Normally Non-Compatible Changes contains the following types:
      1) Package's external services were changed/updated
      2) Package's common .h file is renamed, deleted, or the file path is changed.
      3) The definition of package's common data structure is changed
      ...

 b) "Important Compatible Changes": some important compatible changes can aslo be recorded
    in this file, and we can add these updating into release notes when we release this
    package.

				declared or have no library instance for some library classes, must be
				changed to make sure each library class declared in INF file has
				corresponding library instance.

==========================================================================================
EDK_4096: Non-Compatible: jwang36

      Class_BuildTool:
        1) Removed the calling of vsvars32.bat in edksetup.bat, unless
				"--nt32" switch is used.
				2) Added MAKE command in tools_def.txt. This is used to locate where
				the nmake.exe or make.exe is because it will not be in PATH any more.
				3) Removed the calling of vsvars32.bat in toolsetup.bat.
				4) Solved the hang issue of build.exe when error occurred or Ctrl+C is
				pressed.

        Possible Impacts:
        1) Nt32Pkg build needs to run vsvars32.bat before edksetup.bat or run
				edksetup.bat with "--nt32" option, like

						edksetup.bat --nt32 newbuild

				2) $(WORKSPACE)/Conf/tools_def.txt must be deleted before running
				edksetup.bat because of new tools_def.template. Otherwise the
				build.exe cannot find the nmake.exe to call.
