In 1.4.16, and possibly earlier, the constant in config.h for prctl was renamed to HAVE_SYS_PRCTL_H, but server.c is not checking it correctly on line 763 to see if it should use prctl to set PR_SET_DUMPABLE. Any server running in drop-privs mode, will not be able to dump core even with server.enable-cores set.
