Queued and pushed out.
I wonder if these hits for SA_RESTART in config.mak.uname would be a
good way to guide us.
[6c109904 (Port to HP NonStop, 2012-09-19)]
# Not detected (nor checked for) by './configure'.
# We don't have SA_RESTART on NonStop, unfortunalety.
COMPAT_CFLAGS += -DSA_RESTART=0
[40036bed (Port to QNX, 2012-12-18)]
ifeq ($(uname_S),QNX)
COMPAT_CFLAGS += -DSA_RESTART=0
One caveat is that we do not know if their system headers hide the
real implementation of open(2) behind a C preprocessor macro, in
whcih case OPEN_RETURNS_EINTR wrapper may not work correctly.
