It does, however our build system then explicitly says to the compiler =
'don't use your built-it paths because they may contain declarations =
that contradict the FreeBSD ones' by means of the sysroot argument.  =
When not using an external toolchain, we put the compiler's internal =
headers inside the sysroot.
