From: Alexandre Oliva <ol...@adacore.com>
VxWorks 6 lacks pthread_condattr_setclock, so define CLOCK_RT_Ada to
CLOCK_REALTIME to use the dummy definition of
__gnat_pthread_condattr_setup in libgnarl/thread.c.
socket.c and sysdep.c use FD_ZERO, that relies on bzero on VxWorks 6.
We need to include strings.h to get a declaration for bzero, but don't
require strings.h to exist, since it's nonstandard.
gcc/ada/ChangeLog:
* s-oscons-tmplt.c (CLOCK_RT_Ada) [__vxworks]: Define to
CLOCK_REALTIME on VxWorks6.
* gsocket.h [__vxworks]: Include strings.h if available.
* sysdep.c [__vxworks]: Likewise.
Tested on x86_64-pc-linux-gnu, committed on master.
