            Bug ID: 192394
           Summary: Base system bootstrapping broken with gcc; not clang
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: Any
                OS: Any
            Status: Needs Triage
          Severity: Affects Only Me
          Priority: ---
         Component: conf
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: yaneurabeya at gmail.com

I ran into this build failure after trying to build world @ r269562 with gcc
instead of clang; some of the newly added SCTP constants are undefined in the
header installed in /usr/include/netinet/sctp.h instead of the one installed to
/usr/obj/...:

I removed /usr/obj/usr/src.svn/lib/libc/, restarted the build, I ran into this
issue again. I tried the same thing with my github forked branch as well (just
updated), and ran into the same issue.

We aren’t using -nostdinc/-nostdinc++/-idirafter/-isysroot/-isystem though and
the headers aren’t included with -I, which is probably the underlying issue.

If I use clang, the build “just works” — it picks up the right headers in
.depend and the libc compile goes through properly.
