3778 dnl You might wonder (I did) why epaths.h is generated by running make,
3779 dnl rather than just letting configure generate it from epaths.in.
3780 dnl One reason is that the various paths are not fully expanded (see above);
3781 dnl eg gamedir=${prefix}/var/games/emacs.
3782 dnl Secondly, the GNU Coding standards require that one should be able
3783 dnl to run `make prefix=/some/where/else' and override the values set
3784 dnl by configure. This also explains the `move-if-change' test and
3785 dnl the use of force in the `epaths-force' rule in Makefile.in.
