problems with libstdc++/stl/bitset in 1122 snapshot

[Jeff Sparkes]

First of all, bitset is not included in the list of headers to install
in Makefile.in

Once it is installed, I get error from one of the constructors.  It looks
valid to
me, but I don't claim much C++ knowledge.

There errors are:
/usr/local/egcs/include/g++-2/bitset:630: parse error before `>'
/usr/local/egcs/include/g++-2/bitset:635: warning: ANSI C++ forbids
declaration `_M_copy_from_string' with no type
/usr/local/egcs/include/g++-2/bitset:635: warning: ANSI C++ forbids
initialization of member `_M_copy_from_string'
/usr/local/egcs/include/g++-2/bitset:635: warning: making
`_M_copy_from_string' static
/usr/local/egcs/include/g++-2/bitset:635: ANSI C++ forbids in-class
initialization of non-const static member `_M_copy_from_string'
/usr/local/egcs/include/g++-2/bitset:635: confused by earlier errors,
bailing out

The constructor in question is as follows:

  template<class _CharT, class _Traits, class _Alloc>
  explicit bitset(const basic_string<_CharT,_Traits,_Alloc>& __s,
                  size_t __pos = 0,
                  size_t __n = basic_string<_CharT,_Traits,_Alloc>::npos)
    : _Base()
  {
    if (__pos > __s.size())
      __STL_THROW(out_of_range("bitset"));
    _M_copy_from_string(__s, __pos, __n);
  }

I'm able to proceed by just commenting the constructor out since my code
doesn't use it, but I'm sure somebody cares about the problem.
