Subject: Add equal_to/sort options to nonintrusive trait.
X-Git-Tag: v2.1.0~293^2^2~11
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=49a4821e17e746735168fe56fcc5f05dd1e52b1a;p=libcds.git

Add equal_to/sort options to nonintrusive trait.

Nonintrusive list uses intrusive list as backend, so it is
required to not break the build.
