Btw, I see warnings on GNU/Linux as well, with GCC 4.0.3 and Binutils
2.16.91:

  During symbol reading, incomplete CFI data; unspecified registers (e.g., rax) at 0x444d44.
  During symbol reading, DW_AT_type missing from DW_TAG_subrange_type.

This is when debugging a recent snapshot of GDB with itself.

Does anyone else see this?  Are the compiler and/or Binutils installed
on that system (fencepost.gnu.org) too old?
