- Whether or not stdio console streams are blocking or non-blocking
is now determined at initialization time. The I/O mode is restored before
the program exits. Previously, any changes to the I/O mode would persist.

Added -a switch to cp so that it behaves like Copy CLONE.

- open() no longer examines a file after opening it in order to figure
out whether read/write accesses are permitted. This decision is now
for the file system to make.

- The V37/V40 compatibility code is no longer built for the AmigaOS4
version of the library.

- Switched over the last use of DeviceProc() to GetDeviceProc(), etc.

- Made the <ctype.h> macros more robust.

- Added the baserel directory to the .cvsignore file.

- Replaced ASSERT() macro invocation with assert() call.

- Dropped the special flag variable used by the abort() function that
tracks whether or not console output is possible. We now use the
global "__no_standard_io" instead.

- Removed a misplaced IsInteractive() from the stdio initialization
function. Now this could have been big trouble...

- Removed tests for FileHandle->fh_Type != NULL which used to precede
all IsInterative() tests. I verified that IsInteractive() will always
return FALSE for NIL: type file handles.

- The "char" limits in <limits.h> are now set up according to the current
compiler settings, which can either default to an unsigned or
signed definition.

- Changed the rules again for the use of stderr/stdout redirection when
printing error messages. It is always safe to redirect them now and
no requester will appear unless you specifically set the value of the
"__no_standard_io" variable to TRUE in your program.
