3788 dnl You might wonder (I did) why epaths.h is generated by running make,
3789 dnl rather than just letting configure generate it from epaths.in.
3790 dnl One reason is that the various paths are not fully expanded (see above);
3791 dnl eg gamedir=${prefix}/var/games/emacs.
3792 dnl Secondly, the GNU Coding standards require that one should be able
3793 dnl to run `make prefix=/some/where/else' and override the values set
3794 dnl by configure. This also explains the `move-if-change' test and
3795 dnl the use of force in the `epaths-force' rule in Makefile.in.
