I have the same issue. Although I did manage to get ruby 1.9.2 installed, 1.8.7
died with the same errors you have.  

I also have both rubies working under rvm on my Mac without this issue.

My rvm version on cygwin is: 
$ rvm -v

rvm 1.1.0

Did you ever manage to get ruby 1.8.7 installed in the end?
