From 3426e34feddf97085615e619d39f8173ff3f9fb4 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Mon, 11 May 2009 13:02:18 +0200 Subject: [PATCH] Add NO_CROSS_DIRECTORY_HARDLINKS support to the Makefile When the installed programs are tar'ed up and installed on a system where bin/ and libexec/git-core/ live on different file systems, we do not want libexec/git-core/git-* to be hardlinks to bin/git.
