An header file like 'header.h': #pragma once #include "./header.h" doesn't work because: 1) both filenames are different, so it will be be included anyway 2) after that it will be included again under the name "././header.h" and so on until it eventually fails with ENAMETOOLONG. Prevent this by stripping leading "./"s in the paths. This is not good enough for testing file equivalence by is enough to avoid the loop.
