### If you add support for a new configuration, add code to this

### the appropriate operating system file.
|
|
|
|
### You would hope that you could choose an s/*.h
|
|
### file based on the operating system portion. However, it turns out
|
|
### that each s/*.h file is pretty manufacturer-specific.
|
|
### So we basically have to have a special case for each
|
|
### configuration name.
|
|
###
|
|
### As far as handling version numbers on operating systems is
|
|
### concerned, make sure things will fail in a fixable way. If
|
|
### /etc/MACHINES doesn't say anything about version numbers, be
|
|

dnl You might wonder (I did) why epaths.h is generated by running make,

|
dnl rather than just letting configure generate it from epaths.in.
|
|
dnl One reason is that the various paths are not fully expanded (see above);
|
|
dnl eg gamedir=${prefix}/var/games/emacs.
|
|
dnl Secondly, the GNU Coding standards require that one should be able
|
|
dnl to run `make prefix=/some/where/else' and override the values set
|
|
dnl by configure. This also explains the `move-if-change' test and
|
|
dnl the use of force in the `epaths-force' rule in Makefile.in.
