Thank you for fixing it!

One can call realpath() with NULL for the second parameter on systems that do
not have MAXPATHLEN/PATH_MAX.  You could also use canonicalize_file_name(), but
this is a GNU C library specific function.

 -- Function: char * realpath (const char *restrict NAME, char
          *restrict RESOLVED)
...
     On systems which define `PATH_MAX'
     this means the buffer must be large enough for a pathname of this
     size.  For systems without limitations on the pathname length the
     requirement cannot be met and programs should not call `realpath'
     with anything but `NULL' for the second parameter.

 -- Function: char * canonicalize_file_name (const char *NAME)
     The `canonicalize_file_name' function returns the absolute name of
     the file named by NAME which contains no `.', `..' components nor
     any repeated path separators (`/') or symlinks.  The result is
     passed back as the return value of the function in a block of
     memory allocated with `malloc'.  If the result is not used anymore
     the memory should be freed with a call to `free'.

Its easy to fix this for natFileChannelImpl.cc.

For natFilePosix.cc it is not so simple - is there a portable alternative to
realpath() that does not require the use of MAXPATHLEN / PATH_MAX ?

[gcc]/libjava/java/io/natFilePosix.cc is also broken due to the usage of MAXPATHLEN.
