[DRE-maint] Bug#933107: ruby-rubymail: Deprecation warnings with Ruby 2.4 (constant ::Fixnum is deprecated)

[Gerald Turner]

Package: ruby-rubymail
Version: 1.1.3-3
Severity: minor

Dear Maintainer,

Executing feed2imap (feed2imap package) produces the following error
output:

  /usr/lib/ruby/vendor_ruby/rmail/header.rb:142: warning: constant ::Fixnum is deprecated

Ruby 2.4 added a deprecation warning for the constant "Fixnum", see:

  https://bugs.ruby-lang.org/issues/12739

Evidently Fixnum can be replaced by Integer throughout the rubymail
source.

Warning: I am not a Ruby programmer, so I may be interpreting this
wrong.
