I've started to analyse the failures caused by having a proper
__cplusplus value, but there seem to be several headers and solutions
involved.  This isn't a problem per se, especially if they also apply to
Solaris 8 and up, which might be the case with only small variations to
the fixes.

Once I have an idea what it takes to make the Solaris headers work with
__cplusplus 199711L, I'll also engage the Solaris engineers to try and
get this stuff (and other fixincludes changes, while we're at it)
integrated.
