2.1.69 and gcc 4.0

[Quentin Spencer]

I'm using a Fedora Core 4 test release with GCC 4. I use a plain 
../configure with no flags and when compiling I get a long list of errors 
beginning with:

g++ -c  -I. -I.. -I../liboctave -I../src -I../libcruft/misc  -I../glob 
-I../glob -DHAVE_CONFIG_H -mieee-fp -Wall -W -Wshadow -g -O2 lex.cc -o lex.o

lex.l: In member function ‘bool 
bracket_brace_paren_nesting_level::is_bracket()’:

lex.l:196: error: ‘bracket_brace_paren_nesting_level::<anonymous enum>’ is/uses 
anonymous type

lex.l:196: error:   trying to instantiate ‘template<class T> template<class U> 
octave_int::octave_int(U)’

I have updated every thing I can think of in the development tools to 
the most recent Fedora releases. Looking at the archives, I see that 
Dmitri reported a successful compilation on February 18, but with some 
configure flags I'm not used to seeing like:

--with-gxx-include-dir=/usr/include/c++/3.4.3

This would seem to make it dependent on having both 4.0 and 3.4 versions 
of GCC installed simultaneously. Does anyone else have any more recend 
build experience with GCC 4, and are there any configure options I 
should try? I also recall that someone reported some GCC bugs that may 
be causing problems compiling octave. What problems did they cause?
