HotSpot build on SPARC/Solaris

[Azeem Jiva]

Trying to build on SPARC/Solaris I get the following error:

"/root/hsx/src/os/solaris/vm/os_solaris.cpp", line 6428: Error: Formal 
argument 6 of type unsigned* in call to recvfrom(int, void*, unsigned 
long, int, sockaddr*, unsigned*) is being passed int*.

It seems the method signature changed in Solaris 11 from int pointer to 
an unsigned pointer.  I can get around the issue by casting fromlen to 
an unsigned pointer, but that's dangerous.  I guess I'm looking for 
ideas for a better solution to this.
