+Subject: [PATCH] gm_utils.cpp: Call clear instead of empty.
+
+Since the intention seem to be to erase the next word, I believe calling empty
+was a mistake and it should have been clear.  Empty does nothing in this
+context.
+
+* src/gm_utils.cpp (wrap_cstr): Call clear.

+Subject: [PATCH] gm_utils.h: Drop std::unary_function.
+
+I am not sure what it does, it is deprecated/removed (depending on C++ version)
+and the advice seems to be that is just is not necessary.  So just remove it.
+
+* src/gm_utils.h (print_f, pair_print_f): Drop std::unary_function.
