The purpose is to provide the dirent functionality which is provided  
by glibc (or similar) so available for gcc (and also mingw) for Visual  
C++, which doesn't have this. plcore.c needs that to browse through a  
directory to search for available dynamic drivers which are then  
opened via libtdl or the interface I wrote for windows. Thinking about  
that, it's actually not needed at all in the install tree, but  
plplotP.h is also in the install tree and there dirent_msvc.h is  
included. Maybe it makes sense to move the whole #if HAVE_DIRENT_H/ 
#endif block to plcore.c since I think we don't need it anywhere else.  
Read also the dirent_msvc.h in plplot/include for license etc.

Regards,
Werner
