From 706457b7bda7fdbab426b8dce83b318908339da4 Mon Sep 17 00:00:00 2001 From: "Dr. Matthias St. Pierre" Date: Sat, 28 Sep 2019 00:45:40 +0200 Subject: Reorganize local header files Apart from public and internal header files, there is a third type called local header files, which are located next to source files in the source directory. Currently, they have different suffixes like '*_lcl.h', '*_local.h', or '*_int.h' This commit changes the different suffixes to '*_local.h' uniformly.
