Note that the donation is from the Bill and Melinda Gates Foundation, not from Bill himself. Granted that the foundation was created by Bill, but it is run by his father. The assets used by the foundation do not come entirely from Bill himself, but also include donations from outside sources.
As a note, the foundation had assets at the end of 2003 totaling nearly $27 BILLION. So, while a $42.6 million dollar donation is nice, it is less than .2% of the Foundation's assets, which are separate from Bill's.
