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.

+a French girl, who had been a governess in their family, and she    \
+had announced to her husband that she could not go on living in	    \
+the same house with him.  This position of affairs had now lasted   \

+the members of their family and household, were painfully	    \
+conscious of it.  Every person in the house felt that there was	    \
+so sense in their living together, and that the stray people	    \
+brought together by chance in any inn had more in common with one   \
+another than they, the members of the family and household of the   \
+Oblonskys.  The wife did not leave her own room, the husband had    \
+not been at home for three days.  The children ran wild all over    \
+the house; the English governess quarreled with the housekeeper,    \
+and wrote to a friend asking her to look out for a new situation    \
+for her; the man-cook had walked off the day before just at	    \
+dinner time; the kitchen-maid, and the coachman had given	    \
