I do not see an option to specific not rrd_daemon, so after removing the glib check in configure.ac, I added still CPPFLAGS to the configure for it to find the include files of the older glib 2.4.17, as otherwise the compile of rrd_daemon.c complains about all the glib includes.

This results still into two errors:

rrd_daemon.c: In function `handle_request_forget':
rrd_daemon.c:1271: error: void value not ignored as it ought to be

This is on the 1.4.2 code, line 822 is:

    assert( g_tree_remove(cache_tree, cfd.keys[k]) == TRUE );

Line 1271 is:

  found = g_tree_remove(cache_tree, file);

In version 2.4.17 g_tree_remove returns void, in version 2.8 and later this changes to Boolean. Function is used once to assert, I think I can just patch that out to not check for TRUE and assert. But the other location at 1271 wants to do something based on the return. Any suggestion if I can patch out the journal_write?
