are detected.
- Modified function return values of 0 and -1 to use macros like OK,
ERROR/SEEK_ERROR instead, to better convey what the purpose of these
values is.

the original file descriptors they are duplicates of. I modified the
function which maps file descriptor numbers to file descriptor
table entries to return the table entries of the original files.
- In the thread-safe library, duplicated stdin/stdout/stderr
descriptors now work like the "real" ones. This is true even if
the "real" ones were closed and only their former aliases remain.

- Dropped unused stub code which is now redundant because of
the constructor/destructor mechanism.

and dirent data operations. That should do it! While the library is
not reentrant (this is not ixemul.library) it should be thread-safe
now. Thread-safe in the sense of POSIX 1003.1c-1995.

parameters (which is by default linked in with libunix.a),
regular expressions can no longer prompt dos.library requesters
to appear. However, to be on the safe side, if you are expecting
to pass regular expressions on the command line, do not use
the wildcard expansion code such as by overriding the library
symbols with dummy functions such as are used in the file
"stdlib_wildcard_expand.c".
- Added a new variable '__open_locale' which can be used to
restrict all library functions to use the "C" language locale
rather than the current system locale settings. In addition
to that, two new functions __locale_exit() and __locale_init()
can be used to close and (re-)open the system locale at a
later time.
- Local ("static") functions are now identified by the STATIC
qualifier. This was done in preparation for changes that will
deal with global and local data and the issue of thread safety.

code which initialized them.
- Reading/changing the errno variable is no longer done directly, but
involves accessor functions.
- References to the HUGE_VAL quantity now involve an accessor function, too.
- Changed the manner in which the __huge_val constant is initialized by
the __math_init() function.

exception are "interactive" files such as console windows. For these
line buffered output is used.
- Whether or not a file is bound to an interactive device, such as a
console window, is now checked and remembered after a file descriptor
has been associated with it.
