>Description:
POSIX.1-2024 removes the following functions.  Those that we still have should be excluded from being declared in header files under the appropriate conditions, which may require some thought to figure out -- something like _POSIX_C_SOURCE - 0 >= 202405L, but not _NETBSD_SOURCE or something.

_longjmp()
_setjmp()
_tolower()
_toupper()
fattach()
fdetach()
ftw()
getitimer()
getmsg()
getpmsg()
gets()
gettimeofday()
ioctl()
isascii()
isastream()
posix_trace_*()
 pthread_getconcurrency()
pthread_setconcurrency()
putmsg()
putpmsg()
rand_r()
setitimer()
setpgrp()
sighold()
sigignore()
siginterrupt()
sigpause()
sigrelse()
sigset()
tempnam()
toascii()
ulimit()
utime()
