3747 dnl You might wonder (I did) why epaths.h is generated by running make,
3748 dnl rather than just letting configure generate it from epaths.in.
3749 dnl One reason is that the various paths are not fully expanded (see above);
3750 dnl eg gamedir=${prefix}/var/games/emacs.
3751 dnl Secondly, the GNU Coding standards require that one should be able
3752 dnl to run `make prefix=/some/where/else' and override the values set
3753 dnl by configure. This also explains the `move-if-change' test and
3754 dnl the use of force in the `epaths-force' rule in Makefile.in.
