[PATCH] Fix preponderance of warnings in libjava from boehm-gc

[Kelley Cook]

Third iteration at fixing the duplicate PACKAGE warnings from boehm-gc 
should be the charm.  The change from the second iteration is that this 
time I grab all the GC_*_THREADS definitions too.

Tom,
My first iteration did as you recently suggested and copied everything 
except PACKAGE and VERSION.

Both Nathanael and Bryce said that the logic for the generated file 
should be to only include definitions that we wish to externally present 
as opposed to only excluding those we know are problematic.  I 
personally agree with them.

Bootstrapped and regtested on powerpc-apple-darwin7.6.0
OK to install?  The hundreds of libjava warnings are a regression that I 
caused, though I do not believe that there is a PR associated with the 
problem.

BTW: Bryce, is CVS's PR18699.out supposed to be a zero byte file?
