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]$

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

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.
