Compiling sources with "#pragma once" with header files in subdirectories may
lead to an internal compiler error in the preprocessor.

(I have stripped my sources down to show this problem)

scenario:
1. The test.cpp includes a header file "a.h", located in the subdirectory "inc".
2. "inc/a.h" includes a header file "b.h" in the base directory.
3. "b.h" uses "#pragma once" and includes "c.h" in the base directory.
4. "c.h" includes "b.h" in the base direcotry
   (recursive include prevented with #ifndef/#define)
5. test.cpp includes an other header file "d.h" in the base directory.
6. "d.h" includes also "b.h"
   This is the point, where the ICE occures.

here is my compile command and the resulting output
(I've used "-H" to show the includes)

gcc -I. -E -o test.i test.cpp -H
. inc/a.h
.. ./b.h
... ./c.h
. d.h
In file included from test.cpp:0:
<internal>:0: interner Compiler-Fehler: Speicherzugriffsfehler
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

I've also found out, that a changed search path with "-I- -I."
prevents the ICE

sample command with output:
gcc -I. -E -o test.i test.cpp -H -I- -I.
. ./inc/a.h
.. ./b.h
... ./c.h
. ./d.h
