Change Details

The C startup code calls exit(), which in turn called __cxa_thread_call_dtors that called fprintf(), so stdio is linked regardless of our effort. MFC after: 2 weeks === Sidenote: This was introduced in rS121010 and I think the goal was to reduce the size of statically linked binary of /bin/echo. In rS308432 a call to err() was introduced, but rewriting it as errexit() would not remove err.c from the statically linked binary either. The space saving was negligible (7944 -> 7528 for FreeBSD/amd64 dynamically linked, or 766656 -> 766416 statically linked).
