[...] I attach an updated patch.  It uses 'lcov' instead of 'gcov' as Stefan suggests, which makes the Makefile target much simpler; and I modeled the 'configure' handling on the existing --enable-gprof switch. The existing --enable-gprof option requires --disable-shared and recommends --enable-all-static, and I have just copied that without understanding why or whether the same applies to gcov. I'll probably commit it soon if there are no objections, even though my testing has been rather limited, as it seems unlikely to cause problems for anyone except those who use it. - Julian
