Macros are substituted by the preprocessor, so there's no difference
between:

	G_fatal_error(ERRMSG_RASTER_OPEN_FILE, mapname);
and:
	G_fatal_error(_("Unable to find raster map <%s>"), mapname);

so far as the resulting object file is concerned.

In either case, the code which is actually compiled will be either:

	G_fatal_error(("Unable to find raster map <%s>"), mapname);
or:
	G_fatal_error(G_gettext(PACKAGE,("Unable to find raster map <%s>")), mapname);

depending upon whether I18N is enabled (in the latter case, PACKAGE
will have been expanded to either "grasslibs" or "grassmods").
