"sol2-6.h doesn't exist anymore in GCC 4.4 and later.  Since the patch won't be
applied to GCC 4.3.x, it must be adjusted.  Why was values-xpg4 only added to
sol2-6.h and not to sol2.h?"

As far as I could tell from the documentation available to me, values-xpg4
didn't exist until Solaris 2.6.  Based on the file names I was thinking
sol2-6.h was for 2.6 and above, where sol2.h had to work for 2.5, etc.

I can adjust it and try it with 4.4, but do we need to be concerned with
Solaris < 2.6?

I will also try to research and adjust for Joseph's questions/comments on
std=gnu* and c++.
