	* notes/component-factory.c (owner_set_cb): Get an
	EvolutionShellClient instead of an Evolution_Shell to match the
	changes in libeshell.

2000-06-29  Peter Williams  <peterw@helixcode.com>

	* configure.in:  Re-enable GNOME_PILOT_CHECK.
	Change AC_MSG_CHECKING([For...]) to [for...]. It's the little
	things that matter.

2000-06-28  Ettore Perazzoli  <ettore@helixcode.com>

	* configure.in: `AM_PATH_GCONF'.

2000-06-27  Peter Williams  <peterw@curious-george.helixcode.com>

	* configure.in (ctime_r): Check for whether ctime_r takes
	two (Linux) or three (Solaris) arguments.
	(AC_OUTPUT): Don't create notes/Makefile twice.

	* acconfig.h: Add CTIME_R_THREE_ARGS to the list.
