Neither one is last time I looked. I’m a lot more uptight about POSIX compliance with code that needs to compile than I am with code that just needs a special /dev file to run, for the simple reason, when using POSIX during the compile stage, I can place the blame on GCC and/or clang if the program doesn’t compile when my program is POSIX and C99 compliant (I was, like many, burned by the C23 changes which made a lot of code which previously used to compile no longer compile).
I actually at one time had a Windows binary which would use Windows proprietary calls to make a “urandom” file (secret.txt was its name) so people could have good entropy on systems using the exact same interface as fopen("/dev/urandom","rb") (i.e fopen("secret.txt","rb")) without needing an actual /dev/urandom.
