* m4: add Werror when checking for compiler flagsEmil Velikov2018-10-301-1/+6
| | | | | | | | | | | | | | | | | Seemingly that at some point clang started accepting _any_ flags, whereas previously it would error out. These days, you can give it -Whamsandwich and it will succeed, while at the same time throwing an annoying warning. Add -Werror so that everything gets flagged and set accordingly.
