I have been working on quite a large project for some time now, and I included <limits> in one of my header-files. When I tried to compile(using Code::Blocks) it told me it couldn't open the file;
dl.exe cannot open file bin\debug\my_project Permission denied
I removed <limits> and restored all code to the state it was before the problem emarged. Same error. I tried using rebuild to remake all files from scratch, and still it wont compile.
