patch 8.0.1466: older GTK versions don't have gtk_entry_get_text_length() commit https://github.com/vim/vim/commit/06b77ef69f252e1ba8a2136dcbed6622bc2371bb Author: Bram Moolenaar <Bram@vim.org> Date: Sun Feb 4 14:32:57 2018 +0100 patch 8.0.1466: older GTK versions don't have gtk_entry_get_text_length() Problem: Older GTK versions don't have gtk_entry_get_text_length(). Solution: Add a function with #ifdefs to take care of GTK version differences. (Kazunobu Kuriyama, closes #2605)

" This test is in a separate file, because it usually causes reports for memory
" leaks under valgrind.  That is because when fork/exec fails memory is not
" freed.  Since the process exists right away it's not a real leak.
