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'.
