3761 dnl You might wonder (I did) why epaths.h is generated by running make,
3762 dnl rather than just letting configure generate it from epaths.in.
3763 dnl One reason is that the various paths are not fully expanded (see above);
3764 dnl eg gamedir=${prefix}/var/games/emacs.
3765 dnl Secondly, the GNU Coding standards require that one should be able
3766 dnl to run `make prefix=/some/where/else' and override the values set
3767 dnl by configure. This also explains the `move-if-change' test and
3768 dnl the use of force in the `epaths-force' rule in Makefile.in.
