Nice to hear that they finally fixed their stuff.

probably working exception handling and rtti. If kde doesn't depend on that
(they better don't if they want to use gcc) then you might have luck with

-fno-rtti -fno-exceptions

(but you have to compile every c++ file with these switches). Also, newer
binutils compress the exception information.

Very mortal lately.
