Richard W.M. Jones went through the (tedious!) process of reviewing all of libguestfs wrt gnulib's latest syntax-check rules, and reported many false positives. In a few cases, I found ways to avoid entire classes of false positives:
1/4 maint.mk: relax sc_prohibit_strcmp, to avoid a false positive 2/4 maint.mk: teach sc_prohibit_magic_number_exit to accept 77 3/4 maint.mk: sc_prohibit_path_max_allocation: don't FP for UNIX_PATH_MAX 4/4 maint.mk: exempt trailing blanks found in "binary" files
