3728 dnl You might wonder (I did) why epaths.h is generated by running make,
3729 dnl rather than just letting configure generate it from epaths.in.
3730 dnl One reason is that the various paths are not fully expanded (see above);
3731 dnl eg gamedir=${prefix}/var/games/emacs.
3732 dnl Secondly, the GNU Coding standards require that one should be able
3733 dnl to run `make prefix=/some/where/else' and override the values set
3734 dnl by configure. This also explains the `move-if-change' test and
3735 dnl the use of force in the `epaths-force' rule in Makefile.in.
