3760 dnl You might wonder (I did) why epaths.h is generated by running make,
3761 dnl rather than just letting configure generate it from epaths.in.
3762 dnl One reason is that the various paths are not fully expanded (see above);
3763 dnl eg gamedir=${prefix}/var/games/emacs.
3764 dnl Secondly, the GNU Coding standards require that one should be able
3765 dnl to run `make prefix=/some/where/else' and override the values set
3766 dnl by configure. This also explains the `move-if-change' test and
3767 dnl the use of force in the `epaths-force' rule in Makefile.in.
