I just had a bootstrap failure on i686-pc-linux-gnu with
CVS mainline of a few minutes ago.
I ran (in an empty directory):
$ ../gcc-4.1/configure --prefix=$HOME --enable-languages=c,f95
$ make bootstrap
...
m -f include/limits.h
cp xlimits.h include/limits.h
chmod a+r include/limits.h
rm -f include/README
cp ../../gcc-4.1/gcc/../fixincludes/README-fixinc include/README
chmod a+r include/README

make: *** [bootstrap] Error 2
The compiler used for bootstrapping was
$ gcc -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gcc-4.1/configure --prefix=/home/ig25
--enable-languages=c,f95
Thread model: posix
gcc version 4.1.0 20050409 (experimental)
I then repeated the bootstrap with gcc version 3.3.5 (Debian 1:3.3.5-12),
the problem didn't occur (bootstrap is running fine in stage3 at
the moment).
