Hmm ... so if this is an array of bools, why isn't it declared bool*
rather than char* ?  (Pre-existing ugliness, sure, but we might as
well fix it while we're here.  Especially since you used sizeof(bool)
in the space calculation.)

I agree that maxaligning the start point of the array is pointless.

I'd write "free chunks in a block" not "free chunks on a block",
the latter seems rather shaky English.  But that's getting picky.

LGTM otherwise.
