3718 dnl You might wonder (I did) why epaths.h is generated by running make,
3719 dnl rather than just letting configure generate it from epaths.in.
3720 dnl One reason is that the various paths are not fully expanded (see above);
3721 dnl eg gamedir=${prefix}/var/games/emacs.
3722 dnl Secondly, the GNU Coding standards require that one should be able
3723 dnl to run `make prefix=/some/where/else' and override the values set
3724 dnl by configure. This also explains the `move-if-change' test and
3725 dnl the use of force in the `epaths-force' rule in Makefile.in.
