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...

- fstat() now works with "NIL:" and "/dev/null", respectively. Not that
it returns much useful information, though.

- Added the fstat() test program.

- The _PC_MAX_INPUT query for file handles now returns the default
buffer size.

- Integrated the new OS4 build makefile collection, as contributed by
Steven Solie. Thank you very much!
