Won't either one work, since "Include" is in the "search path"? Is this causing an actual problem? You have this marked as "compile error", but haven't shown any information about the error, such as what compiler, how it's being invoked, and what the error message is. We need some more information.

If this were to be changed (which I'm not advocating unless there's a real problem), would it be better as "initconfig.h" or "./initconfig.h"? I think they're equivalent.
