Therefore, re-using "log2()" is about as bad as re-using the "strcmp()"
name to implement a function which copies strings.

I should probably use ilog2() then which would at least be consistent with the
powerpc arch.

t.c:2: warning: conflicting types for built-in function 'log2'

And apparently gcc < 4.0 doesn't give the warning.

Eh?  That's gcc 3.4.3 producing that warning.  It probably depends on
the target configuration.

I have to admit I didn't try all versions. So < 4.0 was a guess, based on the
(Debian) versions I have installed on my laptop...
