3713 dnl You might wonder (I did) why epaths.h is generated by running make,
3714 dnl rather than just letting configure generate it from epaths.in.
3715 dnl One reason is that the various paths are not fully expanded (see above);
3716 dnl eg gamedir=${prefix}/var/games/emacs.
3717 dnl Secondly, the GNU Coding standards require that one should be able
3718 dnl to run `make prefix=/some/where/else' and override the values set
3719 dnl by configure. This also explains the `move-if-change' test and
3720 dnl the use of force in the `epaths-force' rule in Makefile.in.
