| 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.) |
