Yep. There is an optional rule somewhere (Unearthed Arcana?) that uses fractional base attack bonuses (which would give the example character +2), but according to core rules the character has a +0 BAB.
Oddly in my games, they are experienceing a major comeback. After 5 years of a single gnome spread around 10+ gmaes (many of which folded) I have suddenly got two surface ones and 1 deep one added to my gmaes. Weird. A surge of gnomes.
