Commit: Fix compile time warnings in conftest.c files

[Nick Clifton <nickc@redhat.com>]

Hi Guys,

  I am applying the patch below to fix a potential compile time warning
  message when gas's configure script runs.

  In addition I have also imported Florian Weimer's patch to the
  libiberty sources (885b6660c17f) which does the same thing there.

  Together these two patches mean that the configure scripts run without
  generating compile time warning messages from modern versions of gcc.

Cheers
  Nick
