You can find the preprocessed UnwindLevel1.c and UnwindLevel1-gcc-ext.c attached.
I first sent it without compression, so it turned out to be over 100Kb and should be approved first before it can make to the mailing list, so I gzipped the files. Expect to get a duplicate of this message when the first copy gets its approval.
