[DRE-maint] Bug#1032485: ruby-fcgi: Incompatible version with ruby >3.0

[Petr Jurasek]

Package: ruby-fcgi
Version: 0.9.2.1-3+b2
Severity: important

Dear Maintainer,

there's new version 0.9.2.2 on github (https://github.com/alphallc/ruby-fcgi-ng)
with compatibility changes. I compared debian source package with new github version and
among other things new construct in ext/fcgi/fcgi.c:
#if !defined(RUBY_API_VERSION_MAJOR) || (RUBY_API_VERSION_MAJOR < 3)
  rb_secure(4);
#endif

rb_secure was removed from ruby3.0. In case of this is impossible to include .so
file. If I use irb on bookworm:
irb(main):001:0> require 'fcgi.so'
<internal:/usr/lib/ruby/vendor_ruby/rubygems/core_ext/kernel_require.rb>:85:in `require': /usr/lib/i386-linux-gnu/ruby/vendor_ruby/3.1.0/fcgi.so: undefined symbol: rb_secure - /usr/lib/i386-linux-gnu/ruby/vendor_ruby/3.1.0/fcgi.so (LoadError)
