Using `GLIBTOP_GUILE' instead of `HAVE_GUILE' so one should be able to use

1998-08-06  Martin Baulig  <martin@home-of-linux.org>

	* include/glibtop/*.h: Using `GLIBTOP_GUILE' instead of `HAVE_GUILE'
	so one should be able to use libgtop without guile in an application
	even if guile is installed.

	* sysdeps/common/mountlist.c: Fixed some `xstrdup' problems.

	* lib/open.c: Now correctly reading server features for
	`GLIBTOP_METHOD_PIPE'.

	* sysdeps/freebsd: New directory.
