--- Comment #5 from Ed Smith-Rowland <3dw4rd at verizon dot net> --- I'm pretty sure I have my arms around this one. Two questions: 1. Any ideas on how to make testsuite cases? Any examples of looking at preprocessed files in the testsuite? 2. Assuming this gets into mainline, how far can we backport?
