'RELENG_4_2_0_RELEASE'.

This commit was manufactured to restore the state of the 4.2-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

Use __strong_reference() instead of __weak_reference() to assure that the

2000-01-29T22:53:55+00:00

weak symbols of the same name are not used.

Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),

2000-01-27T23:07:25+00:00

just use _foo() <-- foo().  In the case of a libpthread that doesn't do
call conversion (such as linuxthreads and our upcoming libpthread), this
is adequate.  In the case of libc_r, we still need three names, which are
now _thread_sys_foo() <-- _foo() <-- foo().

Convert all internal libc usage of: aio_suspend(), close(), fsync(), msync(),
nanosleep(), open(), fcntl(), read(), and write() to _foo() instead of foo().

Remove all internal libc usage of: creat(), pause(), sleep(), system(),
tcdrain(), wait(), and waitpid().

Make thread cancellation fully POSIX-compliant.

Track libc's three-tier symbol naming. libc_r must currently implement

2000-01-12T09:28:58+00:00

the _libc_*() entry points and add *() weak aliases.  This will all
change for the better when libc_r becomes libpthread.

Avoid an infinite loop if the last element of the iov array passed to

writev() has an iov_len of 0.

Add RCS IDs to those files without them.

If a short write, only loop if no error.

Check the access mode in the flags before waiting on a read or a write

1998-06-10T22:28:45+00:00

that might never be possible if the file was not opened in the corrent
mode. This prevents a hang for bad programs. Why do people code like that?

Implement compile time debug support instead of tracking file name and

1998-06-09T23:21:05+00:00

line number every time a file descriptor is locked.

This looks like a big change but it isn't. It should reduce the size
of libc_r and make it run slightly faster.
