* gnome-libgtop-sysdeps.m4 (GNOME_LIBGTOP_SYSDEPS): New file.
(libgtop_sysdeps_dir): sysdeps directory libgtop uses.
(libgtop_use_machine_h): define HAVE_GLIBTOP_MACHINE_H if this
is `yes'.
(libgtop_need_server): we only need the libgtop server, when
this has a value of `yes'. Defines NEED_LIBGTOP and NEED_LIBGTOP
automake conditional.

+dnl This file is intended for use both internally in libgtop and in every program
+dnl that wants to use it.
+dnl
+dnl It defines the following variables:
+dnl
+dnl * 'libgtop_sysdeps_dir'    - sysdeps dir for libgtop.
+dnl * 'libgtop_use_machine_h'  - some of system dependend parts of libgtop provide
+dnl                              their own header file. In this case we need to
+dnl                              define 'HAVE_GLIBTOP_MACHINE_H'.
+dnl * 'libgtop_need_server'    - is the server really needed? Defines 'NEED_LIBGTOP'
+dnl                              if true; defines conditional 'NEED_LIBGTOP'.
