The point of that change of mine 
<http://gcc.gnu.org/ml/gcc-patches/2010-05/msg01381.html> was to eliminate 
an AC_TRY_RUN test that was bad for cross compiling.  I guess this issue 
indicates that we do still need a compile or link test to make sure the 
functions are present - although not testing for any particular bugs in 
them.
