Dev-C++ executes "gcc -MM main.c" and put the output of that into the
Makefile, so that make will handle dependencies.
However, if the output of gcc -MM contains error messages, it's output
will be ignored.

You will also have to #include "main.h" into your main.c in order to
make this work.

There's no reason to click on Compile if everything is already compiled
anyway.
The only reason I can think of is because the user wants to relink the
app, that's why I made Dev-C++ behave like that.
