3731 dnl You might wonder (I did) why epaths.h is generated by running make,
3732 dnl rather than just letting configure generate it from epaths.in.
3733 dnl One reason is that the various paths are not fully expanded (see above);
3734 dnl eg gamedir=${prefix}/var/games/emacs.
3735 dnl Secondly, the GNU Coding standards require that one should be able
3736 dnl to run `make prefix=/some/where/else' and override the values set
3737 dnl by configure. This also explains the `move-if-change' test and
3738 dnl the use of force in the `epaths-force' rule in Makefile.in.
