I'm not so sure about keeping src/solaris as "src shared across the 
unix/X11 family", I'd prefer it be renamed to something that doesn't 
have "solaris" or "sunos" in the name. The reason is that keeping 
solaris in the name means there isn't an obvious location for Solaris 
specific files. If they stay in src/solaris then it means this tree 
requires pre-processing or filtering in the build. We do this today in 
several places with no consistency and it would be nice to get rid of this.

In any case, keeping the directory structure flat as Fredrick suggested 
make sense to me. Whether we will actually or refactor to the point 
where we need sysv, gnu, etc. directories isn't clear to me. I think we 
would be doing well to replace most of the ifdef __solaris__ and ifdef 
__linux__ usages with ifdef <capability>.
