It's against b69 which is the latest release (from Friday).  The
patches are against the IcedTea forest so builds can be tested with
IcedTea as well.

Specifically, you do not seem to have the recent changeset  to set

Er... yes I do:

# Add the source level
LANGUAGE_VERSION = -source 7
JAVACFLAGS  += $(LANGUAGE_VERSION)

# Add the class version we want
TARGET_CLASS_VERSION = 7
CLASS_VERSION = -target $(TARGET_CLASS_VERSION)
JAVACFLAGS  += $(CLASS_VERSION)
JAVACFLAGS  += -encoding ascii
JAVACFLAGS  += -classpath $(BOOTDIR)/lib/tools.jar
JAVACFLAGS  += $(OTHER_JAVACFLAGS)

but these only cover the rt classes and not the bootstrap classes.

I didn't copy this for the 6 changes because I didn't immediately see
the point of using variables just for this single use.  I forgot that
it is possible to override these from the command line, so I've update
the patch:
