This self-written compiler warning, which is hopefully going to be committed into LLVM sources soon, warns about potentially missing `static' keywords, similar to -Wmissing-prototypes. - bin/pax: Move external declaration of chdname and s_mask into extern.h. - bin/setfacl: Move setfacl.c-specific stuff out of setfacl.h. - sbin/mount_fusefs: Remove char *progname; use getprogname(). - others: add `static' where possible.
