The magic behind RubyInline is the rbconfig.rb file. This little Ruby
script contains the build environment used to compile the Ruby
interpreter for your particular platform. When RubyInline compiles
code, it uses the build environment found in rbconfig.rb.

So, the catch is that your machine environment
(compilers/libraries/etc) needs to agree with what is in rbconfig.rb.

For my Ruby/Cywin installation, rbconfig.rb can be found here ...

/usr/lib/ruby/1.8/i386-cygwin/rbconfig.rb
