I've tried to build the shiny new 4.4, but it seems the stage1 compiler has
hiccuped here:

gcc was configured with

../gcc-4.4.0/configure --prefix=/localdata --program-suffix=-4.4.0
--enable-languages=c,c++,fortran --with-gp=/localdata --with-mpfr=/localdata
--with-ppl=/localdata --with-cloog=/localdata
--enable-version-specific-runtime-libs --with-arch=athlon64
--with-tune=athlon64

and built with

make CFLAGS='-O2' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2
-fno-implicit-templates' profiledbootstrap

(on a side note: make died at host-linux.c because SSIZE_MAX is not defined by
my system, so I #defined it and carried on bootstrapping *without* cleaning)

Also, my ClooG config is a bit fishy, but this should not really concern xgcc,
should it?
