ccing musl, libc-test is mostly discussed there.

posix says

"Inclusion of the <semaphore.h> header may make visible symbols defined in the <fcntl.h> and <time.h> headers."

https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/semaphore.h.html

which sounds optional, not guaranteed visibility of O_ open flags in
semaphore.h, but sem_open is expected to be usable with only semaphore.h

https://pubs.opengroup.org/onlinepubs/9699919799/functions/sem_open.html

i'm not sure what is the strict standard requirement here, without
clarification i consider it a libc header issue if an api is not usable
with just the header where it is declared.
