 This apparently happens because Apple has dropped support for the
 RLIMIT_AS argument to the setrlimit() syscall in Monterey. The
 documentation of syscall.c in the distribution mentions that this argument
 is also missing in OpenBSD and the author has provided an #ifdef to
 isolate the offending code for that operating system. It's not clear why
 this #ifdef doesn't also work for macOS.

 It seems to me that the easiest fix for this would be to undef RLIMIT_AS
 in the compile options, although I am no programmer so I may have
 misunderstood the problem.

 FYI the homebrew folks have patched the code in syscall.c,
 https://github.com/Homebrew/homebrew-core/issues/88570

 I have emailed the developer of vsftpd who has not replied.
