[PATCH FOR REVIEW]: Make source/target options explicit for CORBA bootstrap tools

[Jonathan Gibbons]

Andrew,

If this is a patch for jdk7, it does not appear to be a patch to a  
recent copy
of 7. Specifically, you do not seem to have the recent changeset  to set
the source/target used to compile JDK to 7. [1]

While your patch does not directly conflict with any edits in that  
patch, and
while the effect of your patch looks OK, in that patch I was extending  
the
precedent of TARGET_CLASS_VERSION to have an explicit macro for
(just) the version number, so that it is easy to change the value of  
(just)
the version number from the command line.

With that in mind, I would suggest something like the following for your
patch:

BOOT_SOURCE_LANGUAGE_VERSION = 6
BOOT_TARGET_CLASS_VERSION = 6
BOOT_JAVACFLAGS  += -encoding ascii -source $ 
(BOOT_SOURCE_LANGUAGE_VERSION) -target $(BOOT_TARGET_CLASS_VERSION)
