Mingw doesn't like directory paths with spaces in them.  But when 
it's inconsistent about the error.   Try putting this in 
D:\CodingStuff\Dev-Cpp\Examples etc., etc.

I had the same problem because I was putting my code in a 
subdirectory of My Documents.  I had about 6 or 7 .h/.cpp files in 
this one project and I was able to compile them just fine... then out 
of the blue, it stopped working.  Couldn't figure it out for the life 
of me.  Then someone in another group told me about the problems it 
has with spaces.  Moved all my source to a spaceless directory path 
and... voila!... everything worked again.

Give it a shot.
