obtained gcc-4.6.4.tar.bz2 from upstream website;upstream

verified gcc-4.6.4.tar.bz2.sig;
imported gcc-4.6.4 source tree from verified upstream tarball.

downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.

if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective
files in the upstream repository.

+# This script is used when compiling Classpath with gcj.  The idea is
+# to compile one package at a time, and only recompile packages when
+# actually required.
+
+# We build java->class by package so we need to know what .java files
+# correspond to what package.
+
+# We have a .stamp file for each package; this is the makefile target.
+# We also have a .list file for each package, which lists all the
+# input files in that package.
+
+# gen-classlist.sh makes a list of all the .java files we are going to compile.
+
+# This script generates Makefile.deps, which looks like this:
+# 
+# java/awt/AWTUtilities.class: lists/java-awt.stamp
+# lists/java-awt.list: /home/aph/gcc/gcc/libjava/classpath/gnu/java/awt/AWTUtilities.java
