Summary: al_findfirst fails to find read-only or archive files

Initial Comment:
In wfile.c, al_findfirst(), there is this snippet:

ff_data->attrib = attrib | 0xFFFFFF00;

   ff_data->handle = _findfirst(uconvert_toascii
(pattern, tmp), &ff_data->data);

(code deleted)

   if (ff_data->data.attrib & ~ff_data->attrib) {
      if (al_findnext(info) != 0) {
         al_findclose(info);
         return -1;
      }
      else
         return 0;
   }

This code returns -1 from the function if there are 
ANY file attributes set in the low byte. This includes 
the archive and read-only bits. Acccording to MSDN, 
the archive bit is set when a file is changed, and 
cleared by the backup command.

This assumes that the binary files match the source 
files, naturally. My discovry of this was while 
debugging a crashing MSVC6 project, and confirmed by 
copying the function and renaming it so I could debug 
it.
