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

+The GNU Classpath tools are stored in the tools.zip. They can be invoked by
+putting this archive into classpath and specifying the tool main class as the
+class to run (parameters usually follow). The current release contains the
+following tools:
+
+== GIOP tools ==
+
+GIOP tools are used for creating the applications that use GIOP communication
+protocol. It provides necessary support for org.omg.* and javax.rmi.* 
+packages.
+
+All GIOP tools support the --help option, for instance:
+  java -cp tools.zip gnu.classpath.tools.giop.IorParser --help
+
+The list of the currently available GIOP tools (name matches the main
+class in gnu.classpath.tools.giop package):
+
+* GRMIC -                RMI-IIOP stub and tie generator.
+* NameService  -         GIOP transient naming service (this tool is called 
+                         tnameserv in Sun's package).
+* NameServicePersistent
+               -         GIOP persistent naming service (this tool is called 
+                         orbd in Sun's package).
+* IorParser -            Parses the stringified form of the interoperable 
+                         object references (IOR's).
+                         
+== RMI tools ==
+
+RMI tools provide support for java.rmi package. All tools support 
+the --help key by printing more information, for instance:
+  java -cp tools.zip gnu.classpath.tools.rmi.RMIC --help
+
+The list of the currently available RMI tools (name matches the main tool class
+in gnu.classpath.tools.rmi package):
+  
+* RMIC -                 RMI stub and tie source code generator (complements
+                         the ASM based bytecode generator in the separate
+                         cp-tools project). This tool is only needed for 
+                         research and backward-compatibile applications, as
+                         Classpath supports the 1.5 feature to replace such 
+                         stubs by proxy classes.
+* REGISTRY -             The persistent RMI naming service.                                                   
+* RMID -                 The persistent RMI activation daemon, supports the
+                         java.rmi.activation package.
+  
+== Security tools ==
+
+Security tools (currently) are used for signing and verifying JAR files
+as well as (planned) generating and managing cryptographic tokens and
+credentials.
+
+The list of individual tools, the name of their main class that should be
+invoked by the Java launcher, and a summary of what they provide follows:
+
+* jarsigner              gnu.classpath.tools.jarsigner.Main
+                         A drop-in replacement for the "jarsigner" tool.
