are arithmetic comparison operators binary?

The patch for src/main/arithmetic.c was prepared as follows:

svn co https://svn.R-project.org/R/trunk/
cd trunk
tools/rsync-recommended
# modifications made to src/main/character.c
svn diff > do_grep.diff

The patched sources were successfully compiled and tested as follows:

svn revert -R .
patch -p0 < do_grep.diff
./configure
make
make check
