A testcase

# gcc -MM x.c -Iinclude         
x.o: x.c foo.h include/ansidecl.h include/libiberty.h include/ansidecl.h

include/ansidecl.h is listed twice. Icc 11.1 generates:

[hjl@gnu-6 dep-1]$ /opt/intel/cce/11.1/bin/icc -MM  x.c -Iinclude 
x.o: x.c foo.h include/ansidecl.h include/libiberty.h
[hjl@gnu-6 dep-1]$
