-dnl Test whether system calls are restartable by default on the
-dnl current system. If they are not, we put a loop around every system
-dnl call to check for EINTR (see SCM_SYSCALL) and do not attempt to
-dnl change from the default behaviour. On the other hand, if signals
-dnl are restartable then the loop is not installed and when libguile
-dnl initialises it also resets the behaviour of each signal to cause a
-dnl restart (in case a different runtime had a different default
-dnl behaviour for some reason: e.g., different versions of linux seem
-dnl to behave differently.)
