dnl You might wonder (I did) why epaths.h is generated by running make,
dnl rather than just letting configure generate it from epaths.in.
dnl One reason is that the various paths are not fully expanded (see above);
dnl to run `make prefix=/some/where/else' and override the values set
dnl by configure. This also explains the `move-if-change' test and
dnl the use of force in the `epaths-force' rule in Makefile.in.
