[ECOS] abs() defined in two places

[Grant Edwards]

It looks like my installation of the 1.3.1 headers are defining abs()
in two places: stdlib.h and libkern.h.

------------------------------testit.c------------------------------
#include <stdlib.h>
#include <network.h>

int j;
--------------------------------------------------------------------

$make
arm-elf-gcc -g -mcpu=arm7tdmi -mbig-endian -c -o testit.o -fverbose-asm -Wa,-ahlsn=testit.lst -O0 -D__ECOS -I../ecos/include -Wall  testit.c
In file included from ../ecos/include/machine/param.h:91,
                 from ../ecos/include/sys/param.h:166,
                 from ../ecos/include/network.h:60,
                 from testit.c:2:
../ecos/include/lib/libkern/libkern.h:113: warning: static declaration for abs' follows non-static

arm-elf-gcc -g -mcpu=arm7tdmi -mbig-endian -Wl,-Map,testit.map -nostartfiles -L../ecos/lib -o testit  testit.o -Ttarget.ld -nostdlib


I thought maybe I had my CFLAGS set wrong, but from looking at the include
files, I can't see anything obvious.  (The program works fine, I'm just trying
to get rid of all of the compiler warnings.)
