   8 # IRIX make uses the shell that is in the SHELL variable, which often defaults
   9 # to csh, so put this in to make it use the Bourne shell. In systems where
  10 # /bin/sh is not a Bourne-compatible shell, this line will have to be edited,
  11 # or "make" must be called with a different SHELL= setting.

  16 # The buildname defaults to "<os-type>-<arch-type>". It can be
  17 # overridden by the "build" parameter when invoking make (e.g. make
  18 # build=xxx) This does not provide an override for the OS type and
  19 # architecture type used during the build process; they still have to be
  20 # used for the OS-specific files. To override them, you can set the
  21 # shell variables OSTYPE and ARCHTYPE when running make.
  22 #
  23 # EXIM_BUILD_SUFFIX gets appended to the buildname.  (This enables
  24 # parallel builds on a file system shared among different Linux distros
  25 # (same os-type, same arch-type). The ../test/runtest script honours the
  26 # EXIM_BUILD_SUFFIX when searching the Exim binary.)
