currently configured. It merely blocks the delivery of the respective signal to prevent recursion. - raise() now drops into abort() if a signal handler is set to SIG_DFL. The exception is in SIGINT delivery, which has the effect of printing a different termination message but otherwise program flow takes the same path as abort(). git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@14907 87f5fb63-7c3d-0410-a384-fd976d0f7a62
