target ARM-none-eabi warning: implicit declaration of function 'MIN'


I am traying to build newlib 2.1.0 with arm-none-eabi-gcc -v version
4.8.3 20140228 (release) [ARM/embedded-4_8-branch revision 208322]
(GNU Tools for ARM Embedded Processors)

./configure --target=arm-none-eabi --disable-newlib-supplied-syscalls
--with-gnu-ld --with-gnu-as --disable-shared
--enable-newlib-io-long-long --disable-nls --enable-newlib-reent-small
--disable-libgloss --enable-newlib-io-c99-formats
--disable-newlib-atexit-dynamic-alloc --enable-newlib-global-atexit
--enable-newlib-reent-small --disable-newlib-wide-orient
--disable-multilib --enable-newlib-multithread --enable-lite-exit
--with-cpu=cortex-m3 --with-mode=thumb --disable-multilib
--with-float=soft --disable-libssp --with-no-thumb-interwork
--enable-newlib-register-fini --disable-newlib-mb
--disable-newlib-unbuf-stream-opt CFLAGS_FOR_TARGET="-DMALLOC_PROVIDED
-ffunction-sections -fdata-sections -Wstack-usage=512 -mcpu=cortex-m3
-mthumb -std=gnu99 -mfloat-abi=soft -nostdlib -g3"

[NOTE: I have collected these options from Internet, some of them may
be redundant, without effect, etc.]

I got warning:

../../../.././newlib/libc/search/hash_bigkey.c: In function '__big_insert':
../../../.././newlib/libc/search/hash_bigkey.c:111:3: warning:
implicit declaration of function 'MIN'
   move_bytes = MIN(space, key_size);

It is caused by missing MIN macro definition in newlib/libc/sys/arm/sys/param.h.
