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]$

This testcase is not complete, it does not include foo.h.

------- Comment #4 from pinskia at gcc dot gnu dot org  2009-03-24 01:50 -------
If I do
cat > foo.h << EOF
#include <ansidecl.h>
EOF

I get the duplicated include file but I don;t think it matters as it is
included twice, how does the cpp know they are really the same include file

------- Comment #8 from rwild at gcc dot gnu dot org  2009-03-24 17:49 -------
Why is this a bug?  I'm really curious to know; the manual doesn't document
that -MM output is uniquified.

It is not really a bug, but it is ugly.
