[libdispatch-dev] Solaris portability, dispatch.h - PATCH [4/6]

[Joakim Johansson]

Added the checking for cdefs.h that does not exist on all platforms,  
also added the __BEGIN_DECLS here as they are usually from cdefs.h and  
are not available on Solaris.

Perhaps this should be broken out to a DISPATCH_SHIMS_CDEFS instead?
