Erik Verbruggen 89aa7eb2ab Sema: do not warn about unused const vars if main file is a header
If we pass a header to libclang, e.g. because it's open in an editor in
an IDE, warnings about unused const vars are not useful: other files
that include the header might use those constants. So when -x *-header
is passed as command-line option, suppress this warning.
