+===============================

+
+
+The following files have to be patched to remove the check macro error on OSX
+build. This is also for Boost 1.40.0 !
+This patch is added on revision 2033 (kicad/include/boost directory!)
+So if upgrading to new version apply this if you get the same error.
+See below snippets of the two files that have to be edit.
+Just subsitude check with check_ in both files.
