clib2 Code

- Replaced "char *" pointers with "const char *" pointers.

- ttyname() now calls ttyname_r(). Also, the libunix.a version of ttyname_r()
will produce "/CONSOLE" rather than "CONSOLE:".

- asctime_r() now returns NULL if the buffer is too short to hold even a single
byte of data.

- basename() is not supposed to modify the string it is passed and should
return a pointer to a string which can be modified. Now it does. Same
thing for dirname().

This commit was manufactured by cvs2svn to create tag 'V1_201'.

- Fixed another compiler warning.

- Removed some more compiler warnings.

- If defined, the local environment variable "DISABLE_COMMANDLINE_WILDCARD_EXPANSION"
will disable expansion of wildcard patterns passed on the command line.
Note that if the variable is not set then the global variable
'__expand_wildcard_args' will provide the defaults for the switch that
controls whether the wildcard expansion takes place. And after the
environment variable has been checked, the '__expand_wildcard_args_check'
function pointer can still be used to override the switch.

- Removed a couple more compiler warnings.

- Preparations for release...
