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
0f4f2a88 21# shell variables OSTYPE and ARCHTYPE when running make.

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.)
