final link failed: Invalid argument when including windows.h

I have set up MinGW and Eclipse with CDT for C++ developing on Windows. Everything works great until I #include <windows.h>. As soon as I do that, I get the linker error message c:/mingw/bin/../lib/gcc/mingw32/4.6.2/../../../../mingw32/bin/ld.exe: final link failed: Invalid argument whereby the path at the beginning resolves to C:/MinGW/mingw32/bin/ld.exe.

I have no idea what the error message tries to tell me... so please help me to decrypt it.

Perhaps you are missing one of the linking parameters on the command line.

E.g., you might want to add the -lgdi32 -lkernel32 -luser32 if you use any of WinAPI functions declared in <windows.h>

Since you are getting errors in Eclipse, add these libraries (gdi32, kernel32, user32) here:

Project Proprerties -> C/C++ build -> Settings -> GCC Linker -> Libraries -> "add the library"

(this is taken from eclipse cdt command line input)

Since I actually don't agree to Lol4t0's opinion that this is too localized here is the ugly answer: Reinstalling G++ solved the problem.

I think the problem also could have been that I maybe forgot to install one of the parts listed here (where I got it from) for the first time... but now I recognize the link is completely deprecated (2005). So one should use another anyway.
