[libvirt] [PATCH 0/3] Fix aliasing rules warnings with gcc-4.4

Hi, It seems gcc's strict aliasing rules got stricter with gcc-4.4. The basic rule is that two pointers of different types can't be used to reference the same address in memory. One exception is using a char* and another is when different types are members of a union. I've used unions to fix all the warnings I see with current CVS HEAD. I can't say I like the solution all that much, so if anyone has better ideas ... Cheers, Mark.
