Detail:
  * Fixed dependencies for debug builds in GNUmakefiles/CApp
  * Added -f switch to rm in GNUmakefiles/StdTools to make it fail silently
    if the file doesn't exist, like the RISC OS version
  * Fix for amu complaining if INSTTYPE is undefined in Makefiles/CApp
  * Reflected makefile changes in resgen, squeeze and xpand in CTools
    component file
  * Added a8time to ModuleDB and CTools component file
Admin:
  Tested in  a C Tools build

Version 5.03. Tagged as 'BuildSys-5_03'

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.
