3747 | dnl You might wonder (I did) why epaths.h is generated by running make, |
3748 | dnl rather than just letting configure generate it from epaths.in. | |
3749 | dnl One reason is that the various paths are not fully expanded (see above); | |
3750 | dnl eg gamedir=${prefix}/var/games/emacs. | |
3751 | dnl Secondly, the GNU Coding standards require that one should be able | |
3752 | dnl to run `make prefix=/some/where/else' and override the values set | |
3753 | dnl by configure. This also explains the `move-if-change' test and | |
