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.
