>Environment:
NetBSD build 10.0 NetBSD 10.0 (GENERIC) #0: Thu Mar 28 08:33:33 UTC 2024  mkrepro@mkrepro.NetBSD.org:/usr/src/sys/arch/amd64/compile/GENERIC amd64
>Description:
POSIX.1-2008 added O_EXEC to fcntl.h
>How-To-Repeat:
Use `#define _POSIX_C_SOURCE  200809L` without also defining `_NETBSD_SOURCE` and try to use O_EXEC.
>Fix:
Untested patch but very likely correct:
