Did I use the wrong header files back at issue #12 ?

ogoffart commented 5 years ago

These warning are in the llvm headers themselfs. Not much can be done about it. Maybe adding the -Wno-strict-aliasing compile option.

Maybe adding the -Wno-strict-aliasing compile option.

That's what I thought too. Thanks.
