octave warnings

[Paul Kienzle]

Some results from a cygwin build of octave 2.1.63 with gcc 3.2

====== compiler warnings ======

glob/glob.c
  813, 932, 988, 1378
        passing arg 0 of 'my_realloc' from incompatible pointer type

libcruft/misc/f77-fcn.c 63
  63
        function declared 'noretern' has a 'return' statement

liboctave/getopt.c
  354,355 (_getopt_initalize)
        unused parameter argc, argv
  528 604 607 (_getopt_internal)
        implicit declaration of function strcmp strncmp strlen
  649 (_getopt_internal)
        suggest explicit braces to avoid ambiguous 'else'

src/c-file-ptr-stream.cc
  134 (seekoff)
        unused parameter streamoff offset, std::_Ios_Seekdir dir
  151 (seekpos)
        unused parameter std::streampos offset

src/oct-procbuf.cc

        octave_procbuf*octave_procbuf_list defined but not used

src/ov-typeinfo.cc

  90 (nargout_count)
        unused variable tree_expression*elt

src/DLD-FUNCTIONS/det.cc
  42 (Fdet)
        unused parameter int nargout


======= test results =======

  eval-catch 1 2, eval 2, global 4, prefer 25,  while 1
        expected blank and got blank;  these are the only blank sets
  eval-catch 8, try 8
        expected a, b but got b, b
  eval-catch 9, try 9
        expected b, b but got
        "ans = error: rethrow: error: `a' undefined near line 2 column 10"


And I'm still getting 'error: Permission denied' when exiting from 
Octave.
Hopefully I will have a new build soon so you all can test it on your
machines and see if it persists.
