Comment (by kencu):

 Aha.

 Tiger has {{{log2l(x)}}}:
 {{{
 $ cat kentest.c
 #include <math.h>
 #include <stdio.h>
 #include <stdint.h>

 int main() {
     uint32_t  pagesize = 4096;
     printf("%u %d %f \n", pagesize, (uint32_t)log2l(pagesize),
 log2l(pagesize));

     return 0;
 }
 }}}

 then:
 {{{
 $ gcc-mp-7 -o kentest2 kentest.c
 $ ./kentest2
 4096 12 12.000000
 }}}

 So that appears to be the answer to the log2 mystery.
