why not just switch to a newer compiler?

Replying to djowel:

why not just switch to a newer compiler?

I personally do use a newer compiler, but I am maintaining a public R package that depends on Boost. Sadly, the officially supported CRAN compiler for Windows is still mingw's g++ 4.6.3 and some users nevertheless prefer to use its incomplete c++0x standard. Another R package maintainer is facing the same problem

https://www.r-project.org/nosvn/R.check/r-release-windows-ix86+x86_64/odeintr-00install.html

If you would like me to use my hack fix, I would understand. But mingw 4.6.3 is still listed as on the Boost webpage as one of the "primary test compilers" for Windows, although I guess without the -std=c++0x flag.

I will be investigating in this weekend.

Joel, is it reasonable for 1.59.0 release? Because I think the fix (perhaps not only for unused.hpp) will affect all around fusion's code.

Sure. OK, let's do it.

milestone To Be Determined → Boost 1.59.0

Ah, I misunderstood, it's not a big deal. OK, now I opened a PR to fix this issue: https://github.com/boostorg/fusion/pull/96 .

Joel, it should be fixed in 1.59 release. Please close this ticket.
