 This is odd, because I'm also using such an architecture and I'm not
 seeing the failure you're reporting. I have:
 
   % as --version
   GNU assembler 2.12.90 20020707
 
 and
 
   % ld --version
   GNU ld version 2.12.90 20020707
 
   % nm libstdc++.so | c++filt| grep _float_
   00099298 R std::__glibcpp_float_QNaN
   0009929c R std::__glibcpp_float_SNaN
   00099294 R std::__glibcpp_float_infinity

   000992ec R std::__glibcpp_long_double_denorm_min
 
 What do you get?
