gcc(0614 cvs) compile error on solaris 8

[vergence <imyaman at account dot kouf dot org>]

on solaris 8 for x86, I tried to compile gcc...(source from cvs)

i configured with following options...
../configure --prefix=/export/home/imyaman/local --enable-shared
--enable-threads=pthread --enable-languages=java,objc --enable-libgcj
--enable-nls 

and typed make bootstrap
