I'm guessing you have a --enable-checking=release build, and that this
is happening in stage2. My testing was with a debug build.
Sorry about this.
Does the attached patch fix it for you? (I verified that it builds
without warnings with both plain and --enable-checking=release
configurations; bootstrapping it now)

Subject: [PATCH] input.c: move test functions within #CHECKING_P and into
selftest::
gcc/ChangeLog:
* input.c (get_source_range_for_char): Rename to...
(selftest::get_source_range_for_char): ...this, and move within
the #if CHECKING_P guard.
(get_num_source_ranges_for_substring): Rename to...
(selftest::get_num_source_ranges_for_substring): ...this, move within
the #if CHECKING_P guard, and make static.
