Fails in some systems with: util/data.c: In function 'open_file_write': util/data.c:99: error: 'O_CLOEXEC' undeclared (first use in this function) util/data.c:99: error: (Each undeclared identifier is reported only once util/data.c:99: error: for each function it appears in.) mv: cannot stat `/tmp/build/perf/util/.data.o.tmp': No such file or directory just FYI, I'll get this fixed.
