Fully expanded version is preferred. Moreover, this doesn't need to be
in the header file at all - esp. if the macros using it are just in .c.
But since we have other typedefs there, I can live with that. One day,
I'll rewrite libvirt-php so that my eyes don't bleed when I open the
sources.
Anyway, for now I'll fix this before pushing.
