Looks like this is because the default mode for C++ in GCC 6 is -std=gnu++14 instead of -std=gnu++98.
Managed to get it to build locally by putting append-cxxflags -std=gnu++98 append-cppflags -std=gnu++98 append-cflags -std=gnu++98 in to src_configure and src_compile. I know this might be superfluous but it was a brute force test with a hammer. cxxflags alone didn't work.

I know this might be superfluous but > it was a brute force test with a hammer. cxxflags alone didn't work. Wes, exactly what does src_compile and src_configure look like after adding this? I seem to have the same problem using gcc-6.4.0 and would like to just get slic3r up and running even if it involves a solution like yours.
I ported the code to be c++11 and newer compatible. Please test. Note also that 1.1.7 seems fine as-is. commit 774e1f608b1a4497ff097fac97d38b3722ee4e29 (HEAD -> master) Author: Ian Stakenvicius <axs@gentoo.org> Date: Wed Sep 27 11:46:18 2017 -0400 media-gfx/slic3r: make v1.2.9 code c++11 compatible for gcc6+ Bug: http://bugs.gentoo.org/622338
