[AC_REQUIRE([AM_WITH_NLS])dnl
## With gettext <= 0.10.35, localedir used to be defined as
## localedir='${prefix}'"/$DATADIRNAME/locale"
## DATADIRNAME being set to share (or lib) by AM_GNU_GETTEXT. So this
## path had nothing to do with datadir and when Heroes was configured
## with --prefix=/usr --bindir=/usr/games --datadir=/usr/share/games as
## the FHS requests for games, locale data would go into
## /usr/share/locale.
##
## In gettext >= 0.10.36, localedir is defined as
## localedir='${datadir}'/locale
## Thus with the same configuration locales will go into
## /usr/share/games/locale.
##
## The FHS is fuzzy enough to let both setups be seen as correct.
##
## Another important point is that there is no way to change the
## locales installation path. `make localedir=/somewhere/else install'
## will NOT work because we need to know the real $localedir path at
## configure time (this macro compute a relative path between $prefix
## and $localedir).
##
## Ideally there should be a --localedir option to configure to set
## this path. Both Akim Demaille (Autoconf) and Bruno Haible (Gettext)
## are aware of this problem. Gettext needs Autoconf support before
## changing its macros and Makefiles, but Autoconf 2.50 is about to be
## released and won't include that change. So this is unlikely to be
## solved anytime soon. Since such change will probably involve an
## update of the GNU Standards, Bruno said he will contact RMS.
##
## By the meantime, if people do need to be able to change the localedir
## path it should be possible to add a option such as
## --enable-localedir=DIR or --with-localedir=DIR. This requires
## going through the trouble of patching gettext's m4 macro and Makefiles.
