Bug #7227: failed to build native extension for bcrypt-ruby gem under cygwin on windows xp

Target version: 1.9.3
ruby -v: 1.9.3-p286


I am setting up a testing agent on Windows XP for a Rails App. This question was posted by me on Stackoverflow, where, members of the community suggested that this was in fact a Ruby Bug I should report here. For consistency purposes, the original StackOverflow Post can be found here:
http://stackoverflow.com/questions/13057452/failed-to-build-native-extension-for-bcrypt-ruby-gem-under-cygwin-on-windows-xp

To enforce consistency between Agents, I am installing it through Bundler with RVM with Cygwin.

The following is the result of running bundle install in the project directory(EDIT: Note that running gem install bcrypt-ruby produces identical output):

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

An error occurred while installing bcrypt-ruby (3.0.1), and Bundler cannot continue.
Make sure that `gem install bcrypt-ruby -v '3.0.1'` succeeds before bundling.
the cygwin gcc package is installed:

as is bcrypt:

 $ whereis bcrypt
 bcrypt: /bin/bcrypt.exe /usr/bin/bcrypt.exe /cygdrive/e/Cygwin/bin/bcrypt.exe /usr/share/man/man1/bcrypt.1.gz

 bcrypt -v
 bcrypt: unknown option -- v
 Usage is: /bin/bcrypt -[orc][-sN] file1 file2..
   -o Write output to standard out
   -r Do NOT remove input files after processing
   -c Do NOT compress files before encryption
   -sN How many times to overwrite input files with random data
Results of further research:

Setting

        rvm use system
(in my case 1.9.3-p286) allows bcrypt-ruby to install without incident

Installing 1.9.3-p286 through rvm and setting

        rvm use 1.9.3-p286
Results in an identical (bar the ruby version) error message.

Installing on Mac OS X works without a hitch on numerous developer stations and several Mac Agents.
