This change in Pike/7.0/src/block_alloc.h 2001-07-04:

  $ cvs di -r 1.19 -r 1.20 src/block_alloc.h | grep my_log2
  <   extern int my_log2(unsigned INT32 x);
  >   extern int my_log2(size_t x);

gives the compilation error below because my_log2 is declared as int my_log2(unsigned INT32 x) is stuff.[ch].
