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 # If a build name has not been specified by running this make file via a
17 # command of the form "make build=xxxx", then determine the name of the
18 # operating system and the machine architecture and use that. This does not
19 # provide an override for the OS type and architecture type; they still have
20 # to be used for the OS-specific files. To override them, you can set the
21 # shell variables OSTYPE and ARCHTYPE when running make.

23 # EXIM_BUILD_SUFFIX should be used to enable parallel builds on a file

26 # EXIM_BUILD_SUFFIX when searching the Exim binary.
