From 717f308e7624233e2ad18fba62558a421dfda83d Mon Sep 17 00:00:00 2001 From: Todd Short Date: Thu, 3 May 2018 11:17:49 -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.
