Suppress "String literal warnings"

I'm trying to suppress the "String literal converted to char*" warnings from the C++ compiler. I found documentation that says I can do this with the -erroff option and that -errtags=yes will show me the tag to use. With -errtags=yes, I see:

"disk_space.cpp", line 85: Warning, wbadinitl: String literal converted to char* in initialization.

In place of wbadinitl, I also see badargtypel2w and wbadasgl. If I add -erroff=wbadinitl,badargtypel2w,wbadasgl, I then get warnings that these are bad message tags! What is the correct tag to suppress these warnings?
