This is from "nagios-plugins-HEAD-200610082352.tar.gz"

It seems to compile ok:
===
if gcc

-DHAVE_CONFIG_H -I. -I. -I.. -I.. -I../lib -I../intl

check_swap.o check_swap.c; \
then mv -f ".deps/check_swap.Tpo"
".deps/check_swap.Po"; else rm -f
".deps/check_swap.Tpo"; exit 1; fi

This appears to be the code at issue ( the SVR4 flag is
in effect rather than the BSD one)

#  ifdef CHECK_SWAP_SWAPCTL_SVR4

  /* get the number of active swap devices */
  nswaps=swapctl(SC_GETNSWP, NULL);

  /* initialize swap table + entries */
 
tbl=(swaptbl_t*)malloc(sizeof(swaptbl_t)+(sizeof(swapent_t)*nswaps));
  memset(tbl, 0,
sizeof(swaptbl_t)+(sizeof(swapent_t)*nswaps));
  tbl->swt_n=nswaps;
  for(i=0;i<nswaps;i++){
    ent=&tbl->swt_ent[i];
    ent->ste_path=(char*)malloc(sizeof(char)*MAXPATHLEN);
  }

  /* and now, tally 'em up */
  swapctl_res=swapctl(SC_LIST, tbl);
  if(swapctl_res < 0){
    perror(_("swapctl failed: "));
    result = STATE_WARNING;
  }
