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.

+// g++ 1.36.1 bug 900121_02
+
+// Assignment of structs is defined as memberwise assignment,
+// however g++ (1.36.2) and Cfront 2.0 differ on the definition
+// of assignment for unions.
+
+// (NOTE: Stroustrup now says that assignment of unions which contain either
+// members or sub-members (base classes are not allowed for unions) which
+// have non-default assignment operators defined for them will be illegal
+// in future.)
+
+// g++ (1.36.2) on the other hand, accepts this program without errors.
+
+// keywords: unions, operator=, inheritance, members
