Warnings when compiling on Mac

[anne-glerum]

I get the following compiler warnings on my Mac:

warning: unknown warning option '-Wno-placement-new' [-Wunknown-warning-option]
warning: unknown warning option '-Wno-literal-suffix'; did you mean '-Wno-literal-range'? [-Wunknown-warning-option]
warning: unknown warning option '-Wno-long-double'; did you mean '-Wno-long-long'? [-Wunknown-warning-option]

@tjhei You helped @Shangxin-Liu to get rid of them already, right?

What is the status of this? @anne-glerum are the warnings still there?

This seems not longer an issue but if it appears again feel free to reopen.
