-Subject: [PATCH] configure.ac: Do not fatalize -Wmissing-prototypes
-
-There comes below error when run "make -C tests/nsm_client nsm_client"
-| nlm_sm_inter_svc.c:20:1: error: no previous prototype for 'nlm_sm_prog_3' [-Werror=missing-prototypes]
-
-It is because rpcgen doesn't generate -Wmissing-prototypes
-free code for nlm_sm_inter_svc.c with below logic
-in tests/nsm_client/Makefile.am
-[snip]
-GENFILES_SVC    = nlm_sm_inter_svc.c
-[snip]
-$(GENFILES_SVC): %_svc.c: %.x $(RPCGEN)
-        test -f $@ && rm -rf $@ || true
-        $(RPCGEN) -m -o $@ $<
-
-So add the logic not to fatalize -Wmissing-prototypes.

+Detect warning options during configure
+
+Certain options maybe compiler specific therefore its better
+to detect them before use.
+
+nfs_error copies the format string and appends newline to it
+but compiler can forget that it was format string since its not
+same fmt string that was passed. Ignore the warning
+
+Wdiscarded-qualifiers is gcc specific and this is no longer needed
