[postgis-users] shp2pgsql problems on Mac OS X Leopard

[Patrick Hartling]

Yes, that is what was happening for me. Without looking at the code, I  
had narrowed it down to some sort of argument processing problem. On  
my way in to the office this morning, I started wondering if it might  
not be better to use the system-provided getopt(3) for the Mac OS X  
case. I could not tell if that was the intention, but I will look into  
that as soon as I can. If I come up with something other than this  
#include removal hack, I will post a patch.
