New Revision: 981763

URL: http://svn.apache.org/viewvc?rev=981763&view=rev
Log:
Revert all but the basename fix from commit r951009:
   These implementations should be portable enough that we don't need the
   #error.

This will break on aix & z/OS until we add platform-specific implementation
for them.
