From: markus schnalke Date: Fri, 10 Feb 2012 14:12:59 +0000 (+0100) Subject: Merged mhlsbr.c into mhl.c. X-Git-Tag: mmh-thesis-end~318 X-Git-Url: http://git.marmaro.de/?p=mmh;a=commitdiff_plain;h=d1da1f94ce62160aebb30df4063ccbc53768656b;ds=sidebyside Merged mhlsbr.c into mhl.c. Also removed the unused function mhlsbr().
