src/oct-gperf.h enum values

[Clinton Chee]

Dear Octave Maintainers

Why is there comilation problem for v 63 but not v 57 of Octave relating 
to the file oct-gperf.h.

Specifically, oct-gperf.h defines a local "enum" structure like this:

enum
  {
    TOTAL_KEYWORDS = 37,
    MIN_WORD_LENGTH = 2,
    MAX_WORD_LENGTH = 22,
    MIN_HASH_VALUE = 2,
    MAX_HASH_VALUE = 75
  };



Later on in oct-gperf.h it uses the MAX/MIN_WORD_LENGTH like:

const struct octave_kw *
octave_kw_lookup (register const char *str, register unsigned int len)
{
  if (len <= MAX_WORD_LENGTH && len >= MIN_WORD_LENGTH)
    {
      register int key = octave_kw_hash (str, len);



This causes problems when compiling but No More Problem if I replace
  if (len <= MAX_WORD_LENGTH && len >= MIN_WORD_LENGTH)
with
  if (len <= 22 && len >= 2)


I am using gperf 3.0.1 for both versions of Octave v57 and v63 but there 
was no problem in the former.

Thanks in advance.

Cheers
Clinton
