/* demonstrate gcc -E bug
 *
 * Tested on:
 * gcc (GCC) 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)
 * Copyright (C) 2004 Free Software Foundation, Inc.
 * This is free software; see the source for copying conditions.  There is NO

 *
 * command: gcc -E -o gcc-E-truncation.E gcc-E-truncation.c
 *
 * Result:
 *
 * - truncated output in gcc-E-truncation.E (no "break").
 *   (The long line stops at 4k characters and all following lines are missing)
 *
 * - gcc returns a 0 status and no diagnostics are produced.
 *
 * Without the -o flag, truncation doesn't happen.
 *
 * Summary: silent truncation.
