For compilers that care.. <sysinclude> adds a search path when one uses
'#include <somefile.hpp>', and <include> adds a search path when one
uses '#include "somefile.hpp"'. In gcc-tools.jam this is not implemented
by using the builtin system vs. user paths options. But instead by
keeping two separate SYSINCLUDE vs. INCLUDE lists and placing the
SYSINCLUDE before the INCLUDE in the gcc invocation. This is because GCC
has additional semantics it puts on what it has as real sysinclude paths
(like turning off warnings). But in cw-tools.jam it's implemented as two
different options because it handles it "correctly".
