I just confirmed that the gcc-4.4.3 packaged in the Android IceCreamSandwich
toolchain ignores -Wno-narrowing.

I suspect that either
  1. A fix was backported to a newer point release of 4.5.  4.5.1 was released
in July 2010, but the newest is 4.5.4, released in July 2012.
  2. The problem is in the LFS setup.
