--- Comment #3 from Tom Tromey <tromey at redhat dot com> 2013-04-29 17:05:34 UTC ---
Ok, I see.  Sorry about that, I misunderstood.

I think the logic in configure.ac for setting this up is not
correct:

build_warnings="-Wall -Wdeclaration-after-statement -Wpointer-arith \
-Wformat-nonliteral -Wpointer-sign \
-Wno-unused -Wunused-value -Wunused-function \
-Wno-switch -Wno-char-subscripts -Wmissing-prototypes \
-Wdeclaration-after-statement -Wempty-body"

# Enable -Wno-format by default when using gcc on mingw since many
# GCC versions complain about %I64.
case "${host}" in
  *-*-mingw32*) build_warnings="$build_warnings -Wno-format" ;;
esac


It seems to me it would be better to try -Wformat only on other
systems like:

diff --git a/gdb/configure.ac b/gdb/configure.ac
index bb7fbdd..7c2080c 100644

 AC_ARG_ENABLE(build-warnings,


Could you give that a try?
You should be able to apply this patch directly to configure if you
can't re-run autoconf.
