So is there someway to force -fno-common to be used with this test or
has that already been done?  It looked to me like the compile time patch

  http://gcc.gnu.org/ml/gcc-patches/2004-07/msg02654.html

to remove the use of complex.h still hadn't been checked in and I
thought maybe it was because of this runtime problem.
