// unsync_streams_from_stdout
//
// When applications are run with the output directed to a file,
// the output can be broken up across multiple lines.
//
// On Unix, output files are streams, not record oriented. On OpenVMS
// you will see this problem when under circumstances such as:
//
// - A batch job (all output goes to the .log file)
// - spawn/out=a.log
// - A subprocess
// - set host/log=a.log
//
// This code fixes that problem.
//
// Note: This fix only works for __USE_STD_IOSTREAM.
// Note: See also: 75-109-857
