Hi,
Here's how the test case: 1. Create the following directory tree: |--include/config.h (may be empty) |--source/config.h (may be empty) \--dbgcnt.c (contains only '#include "config.h"') 2. Go to directory "source" and execute the following commands: gcc -M -I../include -I. ../dbgcnt.c gcc -M -I. -I../include ../dbgcnt.c Result on my system: dbgcnt.o: ../dbgcnt.c ../include/config.h Is this the expected result or smth is wrong?
