Subject: Fix roundup_pow_of_two(1)
From: Rolf Eike Beer <[EMAIL PROTECTED]>
Fix roundup_pow_of_two(1)
1 is a power of two, therefore roundup_pow_of_two(1) should return 1. It
does in case the argument is a variable but in case it's a constant it
behaves wrong and returns 0. Probably nobody ever did it so this was never
noticed.
