This is an automated email from the git hooks/post-receive script.

mbrush pushed a commit to branch master
in repository apps/mousepad.

commit da54cc95d5ae6a8a744dc202cf9d30d20b987b97
Author: Matthew Brush <mbrush at codebrainz.ca>
Date:   Mon Jul 14 16:06:52 2014 -0700

    Use G_DISABLE_CHECKS and G_DISABLE_ASSERT
    
    Instead of using special macro functions everywhere, we can just use
    the g_*() functions and make sure to #define G_DISABLE_CHECKS and
    G_DISABLE_ASSERT and acheive the same effect (although maybe we don't
    want to force these when NDEBUG is defined to let the user define
    themselves for more customization).
    
    Make sure mousepad-private.h is included before any G* files that
    could include glib.h so it properly picks up the defines.
