find usage of gcov-clean target in Makefile.in

Hi, while I do 'make distclean', I find odd `find' usage.

In Makefile.in:
> gcov-clean:
> rm -f gcov-lcov.dat gcov-lcov.log gcov-genhtml.log
> rm -rf gcov-report
> find . -name "*.gcda" -o -name "*.gcno" -exec rm -f -- {} \;

Is it intended below ?
     find . \( -name "*.gcda" -o -name "*.gcno" \) -exec rm -f -- {}\;

I also want to insert `-name ".svn" -prune -or ' to avoid searching
files into metadata directory in working copy, for I can find it
because it takes long time to execute gov-clean target on my jalopy
computer :)

Cheers,
