"/usr/include/stdcxx4/exception.h", line 17: Error: Multiple declaration for std::exception.

This is likely because "On Solaris, standard header <math.h> has a declaration for a struct "exception", as required by standard Unix. If you bring the C++ standard exception class into global scope with a using-declaration or using-directive, it creates a conflict."  (http://docs.sun.com/source/820-4155/c++_faq.html#Coding11)

I assume the akonadi's internal exception.h was meant to be used, so the attached patch does the change and makes akonadi build just fine
