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

+-- THIS GENERIC PROCEDURE IS INTENDED FOR USE IN CONJUNCTION WITH THE ACVC
+-- CHAPTER 13 C TESTS. IT IS INSTANTIATED WITH TWO TYPES. THE FIRST IS AN
+-- ENUMERATION TYPE FOR WHICH AN ENUMERATION CLAUSE HAS BEEN GIVEN, AND THE
+-- SECOND IS AN INTEGER TYPE WHOSE 'SIZE IS THE SAME AS THE 'SIZE OF THIS
+-- ENUMERATION TYPE.
+
+-- THE PROCEDURE ENUM_CHECK IS THEN CALLED WITH THREE ARGUMENTS. THE FIRST IS
+-- AN ENUMERATION LITERAL FROM THE ENUMERATION TYPE, THE SECOND IS AN INTEGER
+-- LITERAL WHICH IS THE VALUE OF THE EXPECTED REPRESENTATION (TAKEN FROM THE
+-- ENUMERATION REPRESENTATION CLAUSE), AND THE THIRD IS A STRING DESCRIBING OR
+-- NAMING THE TYPE (USED IN A CALL TO FAILED IF THE REPRESENTATION CHECK FAILS).
+
+-- THE CHECK IS TO CONVERT THE ENUMERATION VALUE TO A BOOLEAN ARRAY WITH A
+-- LENGTH CORRESONDING TO THE 'SIZE OF THE ENUMERATION TYPE. AN INTEGER TYPE
+-- IS THEN CREATED WITH THIS SAME 'SIZE, AND THE REQUIRED REPRESENTATION VALUE
+-- IS CONVERTED FROM THIS TYPE TO A BOOLEAN ARRAY WITH THE SAME LENGTH. THE
+-- TWO BOOLEAN ARRAYS ARE THEN COMPARED AND SHOULD BE EQUAL. THE CONVERSIONS
+-- ARE PERFORMED USING APPROPRIATE INSTANTIATIONS OF UNCHECKED_CONVERSION.
