3715 dnl You might wonder (I did) why epaths.h is generated by running make,
3716 dnl rather than just letting configure generate it from epaths.in.
3717 dnl One reason is that the various paths are not fully expanded (see above);
3718 dnl eg gamedir=${prefix}/var/games/emacs.
3719 dnl Secondly, the GNU Coding standards require that one should be able
3720 dnl to run `make prefix=/some/where/else' and override the values set
3721 dnl by configure. This also explains the `move-if-change' test and
3722 dnl the use of force in the `epaths-force' rule in Makefile.in.
