    Detail:
     CApp:
      * New variable CLEAN_DEPEND is now the preferred way to specify additional
        clean actions because GNU make doesn't have an equivalent to amu's :: rules
      * Can now indicate preference to use C++ linker options using LINK_TYPE
      * Gains install phase support:
        + INSTALLAPPFILES lists the files to be copied, effectively specified
          relative to LocalRes$Path
        + Adopted INSTTYPE concept from DDE makefiles for cases where executable
          and support files need to be installed to different locations
        + Unusual cases can override this implementation using CUSTOMINSTALLAPP
          and/or CUSTOMINSTALLTOOL
    
      CLibrary:
      * New variable CLEAN_DEPEND is now the preferred way to specify additional
        clean actions because GNU make doesn't have an equivalent to amu's :: rules
      * -o is no longer a mandatory argument to libfile - now in ARFLAGS rather
        than used explicitly
    
      DbgRules / StdRules:
      * Macroised some Norcroft-specific features
    
      HostTools:
      * Clean phase support was incomplete
    
      StdTools:
      * A few additional tool definitions
      * Added macro definitions for common C options
      * C's enable-warnings and suppress-function-name-embedding options now on by
        default because they're usually (maybe even universally?) used - it won't
        hurt if they're specified again by existing makefiles
      * C++ now has equivalent INCLUDES and DEFINES variables, and the standard C++
        headers are on the default include path
      * SEP is defined as the directory separator character and can be used from
        top-level makefiles in a platform-independent way
    
      Functionally equivalent versions of the following makefile fragments
      have been developed so far for executing on a Posix build host:
        AppLibs, CApp, CLibrary, DbgRules, HostTools, StdRules, StdTools
      These suport native compilers (when APCS=Host) and cross-compilers,
      and GCC (when TOOLCHAIN=GNU) and Norcroft toolchains - typically these
      environment variables would be selected by running an Env file.
    
    Admin:
      Tested by building as many as possible of the DDE components on RISC OS
      and on Linux, using native and cross compilers, and using Norcroft and
      GNU toolchains.
