- * Stage 6 Snapshot
- *
- * Revision 4.0.1.6 92/06/11 21:08:16 lwall
- * patch34: some systems don't declare h_errno extern in header files
- *
- * Revision 4.0.1.5 92/06/08 13:00:21 lwall
- * patch20: some machines don't define ENOTSOCK in errno.h
- * patch20: new warnings for failed use of stat operators on filenames with \n
- * patch20: wait failed when STDOUT or STDERR reopened to a pipe
- * patch20: end of file latch not reset on reopen of STDIN
- * patch20: seek(HANDLE, 0, 1) went to eof because of ancient Ultrix workaround
- * patch20: fixed memory leak on system() for vfork() machines
- * patch20: get*by* routines now return something useful in a scalar context
- * patch20: h_errno now accessible via $?
- *
- * Revision 4.0.1.4 91/11/05 16:51:43 lwall
- * patch11: prepared for ctype implementations that don't define isascii()
- * patch11: perl mistook some streams for sockets because they return mode 0 too
- * patch11: reopening STDIN, STDOUT and STDERR failed on some machines
- * patch11: certain perl errors should set EBADF so that $! looks better
- * patch11: truncate on a closed filehandle could dump
- * patch11: stats of _ forgot whether prior stat was actually lstat
- * patch11: -T returned true on NFS directory
- *
- * Revision 4.0.1.3 91/06/10 01:21:19 lwall
- * patch10: read didn't work from character special files open for writing
- * patch10: close-on-exec wrongly set on system file descriptors

- * patch4: character special files now opened with bidirectional stdio buffers
- * patch4: taintchecks could improperly modify parent in vfork()
- * patch4: many, many itty-bitty portability fixes
- *
- * Revision 4.0.1.1 91/04/11 17:41:06 lwall
- * patch1: hopefully straightened out some of the Xenix mess
