Re: Mainline bootstrap failure in libjava, i686-pc-linux-gnu

[Jeffrey Oldham <oldham at codesourcery dot com>]

I got a different bootstrap error in libjava on i686-pc-linux-gnu with
current mainline GCC CVS.  /nfs/oz/home/oldham/gcc/gcc0/configure
--with-gcc-version-trigger=/nfs/oz/home/oldham/gcc/gcc0/gcc/version.c
--host=i686-pc-linux-gnu --prefix=/nfs/oz/home/oldham/gcc-install/gcc0
--norecursion

What is going wrong?  Why do we have "@GCC_3.0" notations in gcc 3.1
code?  When will bootstrapping gcc, any branch, any target, work
consistently?

Thanks for the help,
