I saw this too.  It turns out that Solaris <sys/socket.h> does:

#define bind __xnet_bind

however only when _XOPEN_SOURCE is defined.  That changed with this

I tried undef'ing bind etc. in my libjava tree.  Although that worked
for my build, it feels like a dirty hack to me.

What's the right way to keep the preprocessor from interfering with java
