Solaris checksum bug not in Solaris 10?

Hi nmap-dev,

When I build nmap 4.60 on Solaris 10 using gcc version 3.4.6 and run a 
udp scan against a linux target host, I get 'UDP: bad checksum.'  errors 
on the target and nmap reports all the ports as 'open|filtered'.  
However, in config.h, when I change this:

#define STUPID_SOLARIS_CHECKSUM_BUG 1

to this:

#undef STUPID_SOLARIS_CHECKSUM_BUG

and rebuild the software, nmap runs correctly, reporting that the ports 
are closed, and I don't see the bad checksum errors anymore on the linux 
target.  Maybe that Solaris checksum bug is no longer there in Solaris 10?
