Probably the later ...

Yes ...the two environments do not mix. To run cygwin extensions you
will need cygwin1.dll and to run msvc extensions you will need msvcrt.dll
(which you must find in C:\ruby\bin if you have installed ruby in c:\ruby)

Not at all ... I was able to compile ruby-cygwin and ruby9i extensions
in a matter of about 30 minutes ... most of which were spent in modifying
the Makefile generated by extconf.rb. Let me know if you need help
in this exercise.

None that I can think of ... other than the fact that you can run cygwin
programs only under the cygwin environment.
