patch 8.1.1384: using "int" for alloc() often results in compiler warnings commit https://github.com/vim/vim/commit/964b3746b9c81e65887e2ac9a335f181db2bb592 Author: Bram Moolenaar <Bram@vim.org> Date: Fri May 24 18:54:09 2019 +0200 patch 8.1.1384: using "int" for alloc() often results in compiler warnings Problem: Using "int" for alloc() often results in compiler warnings. Solution: Use "size_t" and remove type casts. Remove alloc_check(), Vim only works with 32 bit ints anyway.
