I have created a free C++ test coverage analysis tool
which is roughly analogous to Rational's purecov
product.  It has been tested on Suse LInux with g++.
See

  http://covtool.sourceforge.net

I used it on log4 and it worked fine.  I am using log4
as a test suite for future product release testing.

I apologize if you feel that posting to this forum is rude
-- I am not sure what the proper etiquet is.  I am sure
someone will tell me (;->)
