Research direction
Start by tracing the existing CI compilation checks and how cc() configures the C standard, noting the current -std=c11 behavior. Done means CI includes a check using --std=c99 that exposes non-standard extensions unless the source explicitly enables them.
Written by the indexing model from the issue text.
Description
As mentioned by @MichaelChirico in https://github.com/Rdatatable/data.table/issues/7517#issuecomment-3704203068, we need a check that hides by default all the non-standard extensions that the code may be using (because they may be hidden by default on e.g. FreeBSD). Then our code will not pass the check without explicitly asking for them (e.g. by #define-ing _POSIX_C_SOURCE). We have hit this problem before when a change that used a C23 feature passed CI but failed with cc() (which now uses -std=c11).
