3719 dnl You might wonder (I did) why epaths.h is generated by running make,
3720 dnl rather than just letting configure generate it from epaths.in.
3721 dnl One reason is that the various paths are not fully expanded (see above);
3722 dnl eg gamedir=${prefix}/var/games/emacs.
3723 dnl Secondly, the GNU Coding standards require that one should be able
3724 dnl to run `make prefix=/some/where/else' and override the values set
3725 dnl by configure. This also explains the `move-if-change' test and
3726 dnl the use of force in the `epaths-force' rule in Makefile.in.
