> Let's say I want to enable multiple warnings. I try:
> {code:bash}
> PYARROW_CXXFLAGS="-Wextra -Wconversion" python setup.py build
> {code}
> and get the following error:
> {code:bash}
> [ 22%] Building CXX object CMakeFiles/plasma.dir/plasma.cxx.o
> g++-4.9: error: unrecognized command line option '-Wextra -Wconversion'
> {code}
> For some reason it seems command expansion doesn't work properly. "{{-Wextra -Wconversion}}" is passed as a single argument instead of two separate ones...
