dnl Boost >= 1.50 uses sleep_for rather than the now-deprecated sleep, however
|
||||
dnl it was broken from 1.50 to 1.52 when backed by nanosleep. Use sleep_for if
|
||||
dnl a working version is available, else fall back to sleep. sleep was removed
|
||||
dnl after 1.56.
|
||||
dnl If neither is available, abort.
|
||||
dnl If sleep_for is used, boost_chrono becomes a requirement.
