There are several places in Ruby where gperf 3.0.4 is assumed.

The newest version of gperf is 3.1. In the long term, we should update Ruby so that it can be compiled with gperf 3.1.

[nobu (Nobuyoshi Nakada)]

Seems the code generated by gperf 3.1 without -n option has a problem with Apple clang.

defs/keywords:57:32: error: implicit conversion loses integer precision: 'size_t' (aka 'unsigned long') to 'unsigned int' [-Werror,-Wshorten-64-to-32]
  register unsigned int hval = len;

This issue may have been fixed with https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=60976. Nobu, please close if that's true.

support gperf 3.1

• tool/gperf.sed: extracted sed commands to a script. ANSI-C code
  produced by gperf 3.1 declares length arguments as size_t. it
  causes conflict with existing declarations, and needs casts for
  a local variable and return statements.
