From: Markus Koschany Date: Sun, 21 Aug 2016 23:33:55 +0200 Subject: boost1.61 libclaw FTBFS with Boost 1.61. error: invalid initialization of non-const reference of type 'double&' from an rvalue of type 'double' See also https://stackoverflow.com/questions/37494170/why-const-double-reference-can-be-assigned-to-int-but-not-non-const-one This is just a work around until we find a proper solution. It has apparently no effects on libclaw's only r-dep plee-the-bear.
