(Sorry for the very late reply.) Although this will increase the complexity of ccache a bit, I think the idea sounds promising. Anyone interested in taking a shot at implementing it? (I only have limited time for ccache right now, and I think other things on my ccache todo list have higher priority than this.) -- Joel _______________________________________________ ccache mailing list ccache@lists.samba.org https://lists.samba.org/mailman/listinfo/ccache
