Subject: Require boost 1.59 or newer.
X-Git-Tag: v9.0.0-rc1~1122^2~1
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d65b09c56da93ef60be128ee7cb197f2a8c001af;p=dealii.git

Require boost 1.59 or newer.

This enables us to use the relatively new boost::container::small_vector
class.
