Makes sense.

That gibes with James Dennett's report that it doesn't appear until
Solaris 10.

Boost.Config may be able to help, but first, what value is __SUNPRO_CC
set to in your environment? And do you know if string.h comes with the
operating system or the compiler? It would be misleading to base choice
on a compiler macro if in fact the header involved ships with the OS. Do
you know if there is a way to discover the version of the operating
system on Solaris?
