We needed this for Boost < 1.48, but per our Wiki on building OSRM:
> On Ubuntu 12.04 you will be limited to OSRM tag v0.3.10 because
> later versions **require Boost v1.49+** and installing this
> causes problems with libluabind-dev package.
Thus, rip it out!
To keep the commits atomic and isolated, I also refactored all call
sites that used the functionality from the portability fix.
While doing this, I also simplified the monster of around ~100 lines of
file path checking --- lambda's are awesome' use them!

Apply `clang-modernize` (based on Clang 3.6) transformations to the
codebase while making sure to support Clang>=3.4 and GCC>=4.8.
We apply the transformations in parallel to speed up the quite
time consuming process, and use our `clang-format` style file
to automatically format the code respecting our coding conventions.
We use the following self-explanatory transformations:
* AddOverride
* LoopConvert
* PassByValue
* ReplaceAutoPtr
* UseAuto
* UseNullptr
This required a `compile_commands.json` compilation database, e.g.
ccmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_EXPORT_COMPILE_COMMANDS=1
for CMake or check Bear for a Makefile based solution (or even Ninja).
git ls-files -x '*.cpp|*.h' | \
xargs -I{} -P $(nproc) clang-modernize -p build -final-syntax-check -format -style=file -summary -for-compilers=clang-3.4,gcc-4.8 -include . -exclude third_party {}
Boom!
