Summary: #include directives don't expand macros as arguments.

Initial Comment:
Hello,
I'm trying to wrap boost::intXX_t types from boost/cstdint.hpp and I'm having problems with #include directives as used in boost headers.

The problem reduces to the fact the following source file fails to be parsed by swig:

%module XXX

#define STDIO "stdio.h"
#include STDIO

when compiled with -importall it says:
testfile.i:5: Error: Unable to find 'STDIO'

I don't know if a ISO C compliant preprocessor is required to expand macro definitions inside an include directive but as I can see that code in boost/config.hpp header I'd bet yes.

Thanks and regards,
Juan
