I'll change:

gfc_change_set			-> gfc_undo_change_set
change_set_var			-> default_undo_chgset_var
changes				-> latest_undo_chgset
gfc_new_checkpoint		-> gfc_new_undo_checkpoint
gfc_drop_last_checkpoint	-> gfc_drop_last_undo_checkpoint
gfc_restore_last_checkpoint	-> gfc_restore_last_undo_checkpoint
free_change_set_data		-> free_undo_change_set_data
pop_change_set			-> pop_undo_change_set


I attach the corresponding patches.
Will test and commit tomorrow.
