The move to write-protected store for macros had not accounted for these runtime additions; fix by removing this protection for "-be" mode. +JH/10 Convert all uses of select() to poll(). FreeBSD 12.2 was found to be + handing out large-numbered file descriptors, violating the usual Unix + assumption (and required by Posix) that the lowest possible number will be + allocated by the kernel when a new one is needed.
