--- Comment #1 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
This seems fixed in GCC 5.0 since now the preprocessed output tracks the
system-header bit within macros:

# 1 "test.c"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "test.c"
# 1 "test.h" 1

# 2 "test.h" 3
# 2 "test.c" 2
int foo(int i, unsigned j) { return 
# 2 "test.c" 3
                                   ((
# 2 "test.c"
                                   i
# 2 "test.c" 3
                                   ) < (
# 2 "test.c"
                                   j
# 2 "test.c" 3
                                   ))
# 2 "test.c"
                                             ; }
