------- Comment #1 from ubizjak at gmail dot com  2009-04-21 10:33 -------
We have a symbol name clash:

This is from libstdc++:

        explicit
        param_type(_RealType __alpha = _RealType(1),
                   _RealType __beta = _RealType(1))
        : _M_alpha(__alpha), _M_beta(__beta)

And this from alpha config:

#define TARGET_CPU_CPP_BUILTINS()                       \
  do                                                    \
    {                                                   \
        builtin_define ("__alpha");                     \
        builtin_define ("__alpha__");                   \

Can libstdc++ define symbol name to something else instead of __alpha?

Sure, this is an annoying recurring issue, I'll fix it momentarily.
