+ /* FIXME: cagney/2002-11-13:
+
+ Method 2a: Use realpath() with a NULL buffer. Some systems, due
+ to the problems described in in method 3, have modified their
+ realpath() implementation so that it will allocate a buffer when
+ NULL is passed in. Before this can be used, though, some sort of
+ configure time test would need to be added. Otherwize the code
+ will likely core dump. */

/* Method 3: Now we're getting desperate! The system doesn't have a
compile time buffer size and no alternative function. Query the
OS, using pathconf(), for the buffer limit. Care is needed
