Ok, got the time, done some checkings.

- RbConfig::CONFIG['host_os']

For several years depending on RUBY_PLATFORM to determine the OS that
host your ruby interpreter was the defacto. Adding host_os to the
Gem.win_platform? will only tackle Gem and projects that:

Directly depend on RubyGems presence to be installed (forget about
package manager using plain setup.rb).

- jruby.bat.exe and the lack of .bat for the generated gems.

This is not complicated to fix, as you stated, but the batch files
generated by RubyGems right now are win32 specific.

I can review the patch If you provide the stub content that need to be
written, based on code it currently generates the stub scripts.

Since these scripts depend on win_platform? being true, we the first
item must be solved before continue.
