2005-12-12 James Henstridge <james@jamesh.id.au> * doc/auto-macros.texi.in: remove unused file. * doc/libgtop2.texi: don't include auto-macros.texi. * doc/Makefile.am: don't build auto-macros.texi, since none of its macros are used in the documentation any more. * include/glibtop/global.h: don't include <config.h> from headers. * .../*.c: make sure <config.h> is the first thing included. * acinclude.m4: m4_include() libgtop-sysdeps.m4 rather than inlining it. * acinclude.m4, libgtop-sysdeps.m4: use third argument to AC_DEFINE() to set the comment. * configure.in: modernise a bit. * acconfig.h: remove file, since it is deprecated * autogen.sh: require automake 1.9 instead of 1.4.
