Well, I decided to remove DevC++ from the equation, using MinGW directly, utilizing Cygwin to give me a competent shell (bash) instead of the windows command prompt. And the good news, it works!
To all that responded to this thread, thanks!

You don't need cygwin to use bash, there's MSYS which is available as an option in the MinGW installer. As for your lock error on using mingw-get, run that command as administrator (the same way you use sudo to install packages on linux). Either way, good you have fixe it.
