This patch can be used to generate a report showing what C source
lines are executed when the testsuite is run. gcc is required. After
applying this patch do:
$ ./configure --enable-gcov
$ make check
$ make gcov
Now look at gcov-report.html and the annotated source files it links
to.
See also gcov(1), gcc(1).
