3784 dnl You might wonder (I did) why epaths.h is generated by running make,
3785 dnl rather than just letting configure generate it from epaths.in.
3786 dnl One reason is that the various paths are not fully expanded (see above);
3787 dnl eg gamedir=${prefix}/var/games/emacs.
3788 dnl Secondly, the GNU Coding standards require that one should be able
3789 dnl to run `make prefix=/some/where/else' and override the values set
3790 dnl by configure. This also explains the `move-if-change' test and
3791 dnl the use of force in the `epaths-force' rule in Makefile.in.
