commit https://github.com/vim/vim/commit/c257487035f83aabe1c7e07f0552309e98f1bcb1 Author: Bram Moolenaar <Bram@vim.org> Date: Thu Aug 11 22:51:05 2016 +0200 patch 7.4.2197 Problem: All functions are freed on exit, which may hide leaks.

# "which" command is not supported everywhere.  Used by Makefile.
