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

+   A tricky, pathological corner case we used to get wrong.  Expansion
+   should go as follows.  The asterisk indicates the token has "blue
+   paint" can no longer be macro expanded.  We used to lose that
+   information when parsing arguments and dropping to the lexer to get
+   the ')'.

+   bar foo* )
+   func (foo* )
+   foo*   
+
+   If we try and expand the final foo, we get an "unterminated
+   argument list invoking macro <func>" error.  If we do the right
+   thing and leave it as is, no diagnostics are emitted.  */
