Hi Gnu Guru's, I have one problem bugging in my project for a long time. It is taking close to 2 hours to compile. There are some other projects with the same size of code which are being built in ~1.15 hours. Are there any GCC switches with which we can know if a same file is being compiled more than once due to wrong includes? Any pointers will be highly appreciated...
