If I recall correctly, I had manually added "-lmingw32" as well as parameters for SDL to my project in Dev C++. I believe this to be the cause of my current trouble. However, I cannot find these anywhere in Code::Blocks.
You should add the Project's libraries to:
Project -> Build Options
Tab "Linker Settings"
Box "Link Libraries"
add in "mingw32" without double quotes or the leading -l.

I wanted to remove it, not re-add it! But you did help me find it, so thanks.
