3723 dnl You might wonder (I did) why epaths.h is generated by running make,
3724 dnl rather than just letting configure generate it from epaths.in.
3725 dnl One reason is that the various paths are not fully expanded (see above);
3726 dnl eg gamedir=${prefix}/var/games/emacs.
3727 dnl Secondly, the GNU Coding standards require that one should be able
3728 dnl to run `make prefix=/some/where/else' and override the values set
3729 dnl by configure. This also explains the `move-if-change' test and
3730 dnl the use of force in the `epaths-force' rule in Makefile.in.
