The compiler can search #include files in several different ways. Implies -cwdexplicit. Use -I- to set the search order as follows:

• For include statements of the form #include "xyz", the compiler first searches user paths, then the system paths
• For include statements of the form #include <xyz>, the compiler searches only system paths
