Thank you very much for your reply.

This sounds interesting. All I want is to record source line coverage, for
dynamic testing and the development of test suites. My program
(http://www.icmb.ed.ac.uk/sokal.html) is ported widely both with and
without my knowledge, and I think a test suite with high coverage would be
a big reassurance for myself and other users. 

Obviously, the tool to do this should be reliable ... are you hesitant to
post the patches because there's still debugging to do, or just because
you have not documented them yet? If simply the latter, I would be
interested in giving them a try. Note, though, I am fairly new to
compiling DJGPP packages and am having quite serious trouble just
compiling the standard GCC 2.8.1 source distribution under Windows 98 (see
also my post to the news group tonight).

Thanks again.


Daniel Barker.
