For log2 to convert 1 << x back to x in case only one bit is set in
expectedVirtTypes.
log2(), including -lm, is rather heavyweight. It should be possible to
use ffs() from <strings.h> to do the same thing, and then we don't have
to worry about dragging in -lm.
I'll work up a patch tomorrow, if no one beats me to it tonight.
