#45 backslashes in #include directives

[Martin Bařinka]

./src/refimpl/E57FoundationImpl.cpp:# include <sys\stat.h>
./src/refimpl/E57FoundationImpl.cpp:# include <sys\stat.h>
./src/refimpl/E57Simple.cpp:# include <sys\stat.h>
./src/refimpl/E57Simple.cpp:# include <sys\stat.h>
./src/refimpl/E57SimpleImpl.cpp:# include <sys\stat.h>
./src/refimpl/E57SimpleImpl.cpp:# include <sys\stat.h></sys\stat.h></sys\stat.h></sys\stat.h></sys\stat.h></sys\stat.h></sys\stat.h>

these includes contain backslashes, which is not correct by standards and probably works only in MSVC, preprocesor should convert regular slashes into backslashes on windows

i am cross compiling using mingw and it does not work
