This sounds more like a configuration error to me. Check the config.log 
for TYPEID_HAS_CLASS to see if it provides any hint as to why this is 
not being defined.

Try removing symbols.oct before building.  If you can't, maybe you are 
running octave with symbols() already loaded?  Windows won't let you 
remove a file if another process has it open.  Maybe renaming it will 
work, but I haven't tried.  Otherwise you will have to quit octave, 
rebuild, and start octave again.
