------- Comment #4 from sam at gcc dot gnu dot org 2008-08-06 16:57 ------- Andrew, you're right, I got confused by the build_binary_op() which is present both in ada/gcc-interface/utils2.c and c-typeck.c, and that the warning appears as is in c-common.c.
The warning is likely to come from tree-vrp.c. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37038
