I might have misrepresented my case.  I am trying to compile a third
party library, and have hit some iostreams compilation problem that
only started hitting with this week's gcc snapshots (ie. it compiled
with last week's gcc).  I tried to isolate
the problem by giving that particular test case.

The actual code has an object (named server) which inherits from iostream.
On the server object, clear() is invoked with:
server.clear(0);

This is causing compilation problems.
I am also getting a lot of template instantiation problems associated
with iostreams that I was not getting last week.

The compiler error messages are here:
http://www.gis.net/~craigr/gcc_error/IOStream.error.txt

and the preprocessed output is here:
http://www.gis.net/~craigr/gcc_error/IOStream_Test.ii.bz2 

I am getting a lot of compiler error messages like:
/opt2/home/craigr/ACE_wrappers/ace/IOStream_T.h:151: no matching function for 
   call to `std::basic_iostream<char, std::char_traits<char> 
   >::operator>>(signed char&)'
/usr/local/include/g++-v3/bits/std_istream.h:92: candidates are: 
   std::basic_istream<_CharT, _Traits>& std::basic_istream<_CharT, 
   _Traits>::operator>>(std::basic_istream<_CharT, 
   _Traits>&(*)(std::basic_istream<_CharT, _Traits>&)) [with _CharT = char, 
   _Traits = std::char_traits<char>]
/usr/local/include/g++-v3/bits/std_istream.h:95:                 
   std::basic_istream<_CharT, _Traits>& std::basic_istream<_CharT, 
   _Traits>::operator>>(std::basic_ios<_CharT, 
   _Traits>&(*)(std::basic_ios<_CharT, _Traits>&)) [with _CharT = char, _Traits 
   = std::char_traits<char>]

I'm not sure how to track it down, because I'm not familiar enough
with iostreams.

Thanks.
