If I understand well this 'bug', it is about the C warnings: 'warning:
implicit conversion shortens 64-bit value into a 32-bit value' in
64-bit.

Well, actually there are hundreds of them:
$ cat make.log | grep 'warning: implicit conversion shortens 64-bit
value into a 32-bit value' | wc -l #=> 375

Here is by file:
$ cat make.log | grep 'warning: implicit conversion shortens 64-bit
value into a 32-bit value' | ruby -e
'ARGF.read.lines.with_object(Hash.new(0)) {|l,h| h[l.split(":")[0]] +=
1 }.each {|f,w| puts f+": #{w}"}'

It would indeed be nice to not have these warnings, but I suppose it
is not so easy to solve.
