[Dev-C++] What changes when I add .rc files?

[Todd G. <pi...@ea...>]

Hello everyone,

What changes when I add.rc files into my project?  What I mean is, I go to
the project menu and select add file.

The reason I am asking is because, I have the project in the environment
dev-cpp version 4.9.8.0 four Windows that seems to act the same whether I
had the .rc file or not.

Thank you,

Todd
