Hello Daniel,
when compiling the current git HEAD with --enable-werror I get two more.
My build environment is Debian Jessie amd64. In order to reproduce this:

        test -d curl || git clone https://github.com/bagder/curl.git
        cd curl
        git reset --hard origin/master; git clean -f -x -d
        ./buildconf
        ./configure CFLAGS='-Os' \
                --disable-ares \
                --disable-cookies \
                --disable-manual \
                --disable-versioned-symbols \
                --enable-hidden-symbols \
                --prefix=`pwd`/../local/linux \
                --disable-shared \
                --disable-manual \
                --disable-libcurl-option \
                --enable-sspi \
                --disable-ftp \
                --disable-smb \
                --disable-dict \
                --disable-file \
                --disable-gopher \
                --disable-imap \
                --disable-imaps \
                --disable-pop3 \
                --disable-pop3s \
                --disable-ldap \
                --disable-ldaps \
                --disable-rtsp \
                --disable-telnet \
                --disable-tftp \
                --disable-smtp \
                --disable-smtps \
                --with-gssapi \
                --enable-ipv6 \
                --without-libidn \
                --without-librtmp \
                --without-libssh2 \
                --without-gssapi \
                --disable-unix-sockets \
                --without-ca-bundle \
                --without-zlib
        make -k

And than I have another one when cross compiling on Debian Jessie amd64 for
win32 using mingw:

(
        cd mbedtls

        test -d mbedtls || git clone https://github.com/ARMmbed/mbedtls.git
        git reset --hard HEAD; git clean -f -x -d
        CC=i686-w64-mingw32-gcc AR=i686-w64-mingw32-ar LD=i686-w64-minggw32-ld CFLAGS="-Os" WINDOWS=1 make -j lib
        make DESTDIR=`pwd`/../local/win32 install
)

(
        test -d curl || git clone https://github.com/bagder/curl.git
        cd curl
        git reset --hard HEAD; git clean -f -x -d
        ./buildconf
        CC=/usr/bin/i686-w64-mingw32-gcc ./configure CFLAGS='-Os' \
                --enable-werror \
                --without-ssl --with-mbedtls=`pwd`/../local/win32 \
                --host=mingw32 \
                --disable-ares \
                --disable-cookies \
                --disable-manual \
                --disable-versioned-symbols \
                --enable-hidden-symbols \
                --prefix=`pwd`/../local/win32 \
                --disable-shared \
                --disable-manual \
                --disable-libcurl-option \
                --enable-sspi \

                --disable-smtp \
                --disable-smtps \
                --with-gssapi \
                --enable-ipv6 \
                --without-libidn \
                --without-librtmp \
                --without-zlib
        make -k
)

  CC libcurl_la-formdata.lo
formdata.c: In function 'FormAdd':
formdata.c:390:21: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
         array_state?(curl_off_t)array_value:va_arg(params, curl_off_t);

If you want an account in order to access the build environment, drop me a ssh
or gpg key.

Cheers,
        Thomas
