Can you post actual contents of (a reduced) $infile that reproduce the problem? The issue doesn't sound familiar, but I cannot decipher your prose into a reproducible case nearly as fast as I could inspect your input files to see if there was an obvious problem either in your input files or in m4 itself. > > The version of m4 I am using is 1.4.13.
