Re: Error compiling network.cpp on Solaris 8

[David Sugar]

Perhaps this could be tied to the _THR_SUNOS5 symbol definition rathern than 
the CEJ_... macro you use?  If so and that works for you and for other 
sun/solaris configurations then it would be self configuring and I think we 
could include this for the next release.
