Subject: Boost 1.61 required for clang/libc++
X-Git-Tag: v4.4.0^2~7
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e23316f453d5ccbd5df24e25e75b3d984cb955f2;p=thirdparty%2Fvectorscan.git

Boost 1.61 required for clang/libc++

The libc++ headers aren't specific enough and causes the compiler to think
there are ambiguous functions when using older Boost versions.
