Comment 1 Jakub Jelinek 2005-05-08 10:23:52 UTC 
The error is correct.  libstdc++-v3 was fixed in GCC 4.0:
2005-01-31  Mark Mitchell  <mark>

        * include/std/std_limits.h (numeric_limits<float>::has_denorm):
        Add required cast.
        (numeric_limits<double>::has_denorm): Likewise.
        (numeric_limits<long double>::has_denorm): Likewise.
Comment 2 Jakub Jelinek 2005-05-27 15:22:43 UTC 
Should be fixed in gcc-3.4.4-1.
