Name collision when using "axutil_dir_windows.h"

This happened when I was trying to write an extension to PERL with the aid of SWIG. I came across two issues as mentioned below.

1. The struct name DIR declared in axutil_dir_windows.h collides with the DIR struct declared in dirent.h that comes with the standard PERL installation.

2. I get the following compile error as a result of the functions opendir, closedir, readdir and rewinddir declared in axutil_dir_windows.h.
error C2059: syntax error : '('.

This should also be due to name conflicts as the file "win32iop.h" that comes with the standard PERL installation has a set of macros defined with similar names.
