   4 Subject: [PATCH] configure.ac: Do not fatalize -Wmissing-prototypes
   5
   6 There comes below error when run "make -C tests/nsm_client nsm_client"
   7 | nlm_sm_inter_svc.c:20:1: error: no previous prototype for 'nlm_sm_prog_3' [-Werror=missing-prototypes]
   8
   9 It is because rpcgen doesn't generate -Wmissing-prototypes
  10 free code for nlm_sm_inter_svc.c with below logic
  11 in tests/nsm_client/Makefile.am
  12 [snip]
  13 GENFILES_SVC    = nlm_sm_inter_svc.c
  14 [snip]
  15 $(GENFILES_SVC): %_svc.c: %.x $(RPCGEN)
  16         test -f $@ && rm -rf $@ || true
  17         $(RPCGEN) -m -o $@ $<
  18
  19 So add the logic not to fatalize -Wmissing-prototypes.
