In general, "Feedback" means that an action of other than assignee is required.
In this ticket, I need a patch for backport which covers r33711, r33713-r33721, r33724, r33727,
r33728, r33752, and r33753.

Backport #6127: IO#ioctl range error in 1.9.3

In 32-bit implementations of 1.9.3 passing an (apparently) unsigned value (BIOCIMMEDIATE = 0x80044270) to ioctl throws range error:

ruby-1.9.3-p125 :001 > a,b = IO.pipe
 => [#<IO:fd 5>, #<IO:fd 6>]
ruby-1.9.3-p125 :002 > a.ioctl(0x80044270, "\x01")
RangeError: bignum too big to convert into `long'
  from (irb):2:in `ioctl'
  from (irb):2

ruby-1.9.3-p125 :001 > 0x80044270.class
 => Bignum

When in 32-bit 1.9.1 and 1.9.2 it does not:

ruby-1.9.1-p243 :001 > a,b = IO.pipe
 => [#<IO:0x202fefc>, #<IO:0x202fec4>]
ruby-1.9.1-p243 :002 > a.ioctl(0x80044270, "\x01")

ruby-1.9.1-p243 :001 > 0x80044270.class
 => Bignum

OS is [x86_64-darwin10.8.0] however ruby was compiled as 32-bit through rvm using:
rvm_archflags="-arch i386" CFLAGS="-arch i386" LDFLAGS="-arch i386" rvm install [ruby-version] --patch osx-arch-fix

The patch is installed in ~/.rvm/patches/ruby/1.9.3/ and is as follows:

this issue appears to be related (http://bugs.ruby-lang.org/issues/5429), but I don't speak Japanese.
