This is a follow-up to c8c4ad0 ("forkfd: Define __BSD_VISIBLE and
_NETBSD_SOURCE").
Defining those macros in forkfd.c is not enough: forkfd_qt.cpp also sets
_POSIX_C_SOURCE, and sys/cdefs.h can be included implicitly via Qt's
headers (<algorithm> ends up pulling unistd.h that leads to sys/cdefs.h
and sys/types.h with both libstdc++ and older libc++ versions). In this
case, __BSD_VISIBLE/_NETBSD_SOURCE are not defined, _POSIX_C_SOURCE is,
several type definitions are omitted and by the time we include
sys/time.h in forkfd.c the build fails. On FreeBSD < 11, the error looks
like this:
In file included from io/../../3rdparty/forkfd/forkfd.c:36,
from io/forkfd_qt.cpp:80:
/usr/include/sys/time.h:94: error: 'u_int' has not been declared
