From 1b3af972c0ea6435ce7ac897de9f7c0f138e05a7 Mon Sep 17 00:00:00 2001 From: Todd Short Date: Mon, 23 Apr 2018 14:06:22 -0400 Subject: [PATCH] Configure: fix Mac OS X builds that still require makedepend Earlier Apple Xcode compilers, e.g. one targeting Mac OS X 10.7, don't support dependency generation and one still has to use makedepend. It's unclear when it was fixed, but all clang-based Apple compilers seem to support -M options.
